IDLE instruction is executed to
put the device into STANDBY mode.
The PLL block responds to the STANDBY signal. SYSCLKOUT is held for 32 cycles
before being turned off. This delay enables the CPU pipeline and any other
pending operations to flush properly. If an access to XINTF is in progress and
its access time is longer than this number then it will fail. TI recommends
entering STANDBY mode from SARAM without an XINTF access in progress.
Clock to the peripherals are
turned off. However, the PLL and watchdog are not shut down. The device is now
in STANDBY mode.
The external wake-up signal is
driven active.
After a latency period, the
STANDBY mode is exited.
Normal execution resumes. The
device will respond to the interrupt (if enabled).
