8.7 Low-power Modes Block

Table 8-22 summarizes the various modes.

Table 8-22 Low-power Modes
MODELPMCR0(1:0)OSCCLKCLKINSYSCLKOUTEXIT(1)
IDLE00OnOnOnXRS, CPU-watchdog interrupt, any enabled interrupt
STANDBY01On
(CPU-watchdog still running)		OffOffXRS, CPU-watchdog interrupt, GPIO Port A signal, debugger(2)
HALT(3)1XOff
(on-chip crystal oscillator and PLL turned off, zero-pin oscillator and CPU-watchdog state dependent on user code.)		OffOffXRS, GPIO Port A signal, debugger(2), CPU-watchdog
(1) The EXIT column lists which signals or under what conditions the low power mode is exited. A low signal, on any of the signals, exits the low power condition. This signal must be kept low long enough for an interrupt to be recognized by the device. Otherwise, the low-power mode will not be exited and the device will go back into the indicated low power mode.
(2) The JTAG port can still function even if the CPU clock (CLKIN) is turned off.
(3) The WDCLK must be active for the device to go into HALT mode.

The various low-power modes operate as follows:

IDLE Mode: This mode is exited by any enabled interrupt that is recognized by the processor. The LPM block performs no tasks during this mode as long as the LPMCR0(LPM) bits are set to 0,0.
STANDBY Mode: Any GPIO port A signal (GPIO[31:0]) can wake the device from STANDBY mode. The user must select which signals will wake the device in the GPIOLPMSEL register. The selected signals are also qualified by the OSCCLK before waking the device. The number of OSCCLKs is specified in the LPMCR0 register.
HALT Mode: CPU-watchdog, XRS, and any GPIO port A signal (GPIO[31:0]) can wake the device from HALT mode. The user selects the signal in the GPIOLPMSEL register.
Note:

The low-power modes do not affect the state of the output pins (PWM pins included). They will be in whatever state the code left them in when the IDLE instruction was executed. For more information, see the System Control and Interrupts chapter of the TMS320x2805x Real-Time Microcontrollers Technical Reference Manual.
