chdog Interrupt bit (EIE.4) and EWT provides information such as
whether the Watchdog Timer event has been encountered or not
and what action should be taken. This bit must be cleared by sof
tware before exiting the interrupt service routine. By using softwa
re to enable the WDIF, a Watchdog interrupt is generated. Enable
d software-set WDIF will generate a Watchdog interrupt. Timed Ac
cess Register procedure can be used to modify this bit.
