Bits 7:4 – WINDOW[3:0] Window Mode Time-Out Period

In Window mode, these bits determine the watchdog closed window period as a number of cycles of the 1.024kHz CLK_WDT_OSC clock.

These bits are loaded from NVM User Row at start-up.

Bits 3:0 – PER[3:0]  Time-Out Period

These bits determine the watchdog time-out period as a number of 1.024kHz CLK_WDTOSC clock cycles. In Window mode operation, these bits define the open window period.

These bits are loaded from NVM User Row at startup.
