5.11.3 CYCLIC WAKE-UP VIA WATCHDOG
(Submit Feedback)To keep the watchdog active when the device is in Sleep mode, the WDSLP bit of the Watchdog Configuration Register 1 must be set to ‘1’. When the device goes into Sleep mode with WDSLP = 1, the Watchdog Timer gets reset and restarts immediately. When the Watchdog is activated during Sleep mode, the Sleep mode current consumption increases by about 20µA compared to IVS_SLP.
