This is the time taken to begin execution of the instruction that immediately follows the IDLE instruction. execution of an ISR (triggered
by the wake up signal) involves additional latency.
A.
B.
IDLE instruction is executed to put the device into STANDBY mode.
The PLL block responds to the STANDBY signal. SYSCLKOUT is held for approximately 32 cycles before being
turned off. This 32-cycle delay enables the CPU pipe and any other pending operations to flush properly.
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).
