There is an on-chip free-running oscillator in NY8A051H which is used by WDT. As this oscillator is independent of other oscillation circuits, WDT may still keep working during Standby mode and Halt mode.
WDT can be enabled or disabled by a configuration word. When WDT is enabled by configuration word, its operation still can be controlled by register bit WDTEN (PCON[7]) during program execution. Moreover, the mechanism after WDT time-out can reset NY8A051H or issue an interrupt request which is determined by another configuration word. At the same time, register bit /TO (STATUS[4]) will be clear to 0 after WDT time-out.
The baseline of WDT time-out period can be 3.5 ms, 15 ms, 60 ms or 250 ms which is determined by two configuration words. The time-out period can be lengthened if Prescaler0 is assigned to WDT. Prescaler0 will be
