29.3.9 Events

An asynchronous event is generated from the LSB of the WDT counter. The event will be identical to the waveform of the LSB of the WDT counter. This feature is useful to verify that the WDT is running. This event is active whenever the WDT clock is active, i.e., also in STANDBY and POWERDOWN sleep modes.

Note: This event will not have a constant period as the LSB of the counter may not change on every WDT clock tick in the case of the window going from OPEN to CLOSED in Window mode, or in the case of a WDR instruction. In these cases, up to three CLK_WDT cycles may pass without the LSB toggling. Any monitoring system must be tolerant of this irregularity.
