assigned to WDT by writing 1 to register bit PS0WDT. The dividing rate of Prescaler0 for WDT is determined by register bits PS0SEL[2:0] and depends on WDT time-out mechanism. The dividing rate is from 1:1 to 1:128 if WDT time-out will reset NY8A051H and dividing rate is from 1:2 to 1:256 if WDT time-out will interrupt NY8A051H.
When Prescaler0 is assigned to WDT, the execution of instruction CLRWDT will clear WDT, Prescaler0 and set /TO flag to 1.
If user selects interrupt for WDT time-out mechanism, register bit WDTIF (INTF[6]) will set to 1 after WDT is expired. It may generate an interrupt request if register bit WDTIE (INTE[6]) and GIE both set to 1. WDTIF will not be clear until firmware writes 0 to WDTIF.
