CUSTOMERS It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and enhanced as new volumes and updates are introduced. If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via E-mail at docerrors@microchip.com or fax the Reader Response Form in the back of this data sheet to (480) 792-4150. We welcome your feedback. Most Current Data Sheet To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at: http://www.microchip.com You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).

Access to the alternate vector table is provided by the ALTIVT bit in the INTCON2 reg- ister. If the ALTIVT bit is set, all interrupt and exception processes will use the alternate vectors instead of the default vectors. The alternate vectors are organized in the same manner as the default vectors. The AIVT sup- ports emulation and debugging efforts by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. If the AIVT is not required, the program memory allo- cated to the AIVT may be used for other purposes. AIVT is not a protected section and may be freely programmed by the user. © 2011 Microchip Technology Inc. DS70143E-page 49

dsPIC30F6011A/6012A/6013A/6014A 9.5.1 RTC OSCILLATOR OPERATION When the TON = 1, TCS = 1 and TGATE = 0, the timer increments on the rising edge of the 32 kHz LP oscilla- tor output signal, up to the value specified in the Period register and is then reset to ‘0’. The TSYNC bit must be asserted to a logic ‘0’ (Asynchronous mode) for correct operation. Enabling the LPOSCEN bit (OSCCON<1>) will disable the normal Timer and Counter modes and enable a timer carry-out wake-up event. When the CPU enters Sleep mode, the RTC will con- tinue to operate provided the 32kHz external crystal oscillator is active and the control bits have not been changed. The TSIDL bit should be cleared to ‘0’ in order for RTC to continue operation in Idle mode. 9.5.2 RTC INTERRUPTS When an interrupt event occurs, the respective interrupt flag, T1IF, is asserted and an interrupt will be generated if enabled. The T1IF bit must be cleared in software. The respective Timer interrupt flag, T1IF, is located in the IFS0 status register in the interrupt controller. Enabling an interrupt is accomplished via the respec- tive timer interrupt enable bit, T1IE. The timer interrupt enable bit is located in the IEC0 Control register in the interrupt controller. © 2011 Microchip Technology Inc. DS70143E-page 69

USIDL = 1, the module will stop on Idle. 16.10 UART Operation During CPU Sleep and Idle Modes 16.10.1 UART OPERATION DURING CPU SLEEP MODE When the device enters Sleep mode, all clock sources to the module are shutdown and stay at logic ‘0’. If entry into Sleep mode occurs while a transmission is in prog- ress, then the transmission is aborted. The UxTX pin is driven to logic ‘1’. Similarly, if entry into Sleep mode occurs while a reception is in progress, then the recep- tion is aborted. The UxSTA, UxMODE, transmit and receive registers and buffers, and the UxBRG register are not affected by Sleep mode. If the WAKE bit (UxMODE<7>) is set before the device enters Sleep mode, then a falling edge on the UxRX pin will generate a receive interrupt. The Receive Interrupt Select mode bit (URXISEL) has no effect for this func- tion. If the receive interrupt is enabled, then this will wake-up the device from Sleep. The UARTEN bit must be set in order to generate a wake-up interrupt. DS70143E-page 108 © 2011 Microchip Technology Inc.

It runs off its own RC oscillator for added reliability. There are two timers that offer necessary delays on power-up. One is the Oscillator Start-up Timer (OST), intended to keep the chip in Reset until the crystal oscillator is stable. The other is the Power-up Timer (PWRT), which provides a delay on power-up only, designed to keep the part in Reset while the power supply stabilizes. With these two tim- ers on-chip, most applications need no external Reset circuitry. Sleep mode is designed to offer a very low-current Power-Down mode. The user can wake-up from Sleep through external Reset, Watchdog Timer Wake-up or through an interrupt. Several oscillator options are also made available to allow the part to fit a wide variety of applications. In the Idle mode, the clock sources are still active, but the CPU is shut-off. The RC oscillator option saves system cost, while the LP crystal option saves power. © 2011 Microchip Technology Inc. DS70143E-page 143

To use the in-circuit debugger cleared, the corresponding module is function of the device, the design must implement ICSP enabled after a delay of 1 instruction cycle (assuming the module control registers connections to MCLR, VDD, VSS, PGC, PGD and the selected EMUDx/EMUCx pin pair. are already configured to enable module operation). This gives rise to two possibilities: 1. If EMUD/EMUC is selected as the debug I/O pin pair, then only a 5-pin interface is required, as the EMUD and EMUC pin functions are multi- plexed with the PGD and PGC pin functions in all dsPIC30F devices. 2. If EMUD1/EMUC1, EMUD2/EMUC2 or EMUD3/ EMUC3 is selected as the debug I/O pin pair, then a 7-pin interface is required, as the EMUDx/EMUCx pin functions (x = 1, 2 or 3) are not multiplexed with the PGD and PGC pin functions. © 2011 Microchip Technology Inc.

dsPIC30F6011A/6012A/6013A/6014A 23.0 ELECTRICAL CHARACTERISTICS This section provides an overview of dsPIC30F electrical characteristics. Additional information will be provided in future revisions of this document as it becomes available. For detailed information about the dsPIC30F architecture and core, refer to “dsPIC30F Family Reference Manual” (DS70046). Absolute maximum ratings for the dsPIC30F family are listed below. Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied. Absolute Maximum Ratings(†) Ambient temperature under bias.............................................................................................................-40°C to +125°C Storage temperature.............................................................................................................................. -65°C to +150°C Voltage on any pin with respect to VSS (except VDD and MCLR)(1)................................................-0.3V to (VDD + 0.3V) Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +5.5V Voltage on MCLR with respect to VSS .......................................................................................................0V to +13.25V Maximum current out of VSS pin...........................................................................................................................300 mA Maximum current into VDD pin(2)...........................................................................................................................250 mA Input clamp current, IIK (VI < 0 or VI > VDD)..........................................................................................................±20 mA Output clamp current, IOK (VO < 0 or VO > VDD)...................................................................................................±20 mA Maximum output current sunk by any I/O pin..........................................................................................................25 mA Maximum output current sourced by any I/O pin....................................................................................................25 mA Maximum current sunk by all ports.......................................................................................................................200 mA Maximum current sourced by all ports(2)...............................................................................................................200 mA Note 1: Voltage spikes below VSS at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latchup. Thus, a series resistor of 50-100Ω should be used when applying a “low” level to the MCLR/VPP pin, rather than pulling this pin directly to VSS. 2: Maximum allowable current is a function of device maximum power dissipation. See Table23-2 for PDMAX. †NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied.
