bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 FWDTEN: Watchdog Timer Enable bit
1 = WDT is enabled
0 = WDT is disabled (control is placed on the SWDTEN bit)
bit 6 WINDIS: Windowed Watchdog Timer Disable bit
1 = Standard WDT is selected; windowed WDT disabled
0 = Windowed WDT is enabled
bit 5 Unimplemented: Read as ‘0’
bit 4 FWPSA: WDT Prescaler bit
1 = WDT prescaler ratio of 1:128
0 = WDT prescaler ratio of 1:32
