54.8 Wake-Up Time
Conditions:
- VDD = 3.3V
- LDO Regulation mode (default mode)
- CPU clock = DFLL48 in open loop (default configuration)
- NVM automatic wait state and cache enabled (default configuration)
Measurement Methods
For IDLE and STANDBY, the exit of mode is done through asynchronous EIC wake-up. The wake-up time is measured between the toggle of the EIC pin and the set of the IO pin done by the first executed instructions in EIC interrupt handler.
For Backup and hibernate, the exit of mode is done through RTC wake-up. The wake-up time is measured between the toggle of the RTC pin (SUPC_BKOUT_RTCTGL) and the set of the IO done by the first executed instructions after reset.
For OFF mode, the exit of mode is done through Reset pin, the time is measured between the rising edge of the RESETN signal and the set of the IO done by the first executed instructions after Reset.
