1.4 Timeout Periods

The WDT offers a wide range of timeout periods, from 8ms to 8 seconds (refer to data sheet for details). The timeout period for the WDT period and the WDT window period is controlled by the WDT Period (PER) bits and the WDT Window Period (WPER) bits located in the WDT Control Register (CTRL) and WDT Window Control Register (WINCTRL).

The WDT is Reset when a valid write access to CTRL or WINCTRL register is performed (refer the description of the timed sequence required to write the control registers found in section Run-time Enabling of the Watchdog Timer).
