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 1.024 kHz 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 1.024 kHz 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.
