initialized back to the entered value every time either of
the registers are accessed. In this manner, controlled
periodic accesses to the Watchdog Timer can prevent
the Watchdog Alarm from going to an active level. If ac-
cess does not occur, countdown alarm will be repetitive.
The Watchdog Alarm Registers always read the en-
tered value. The actual count- down register is internal
and is not readable. Writing registers C and D to zero will
disable the Watchdog Alarm feature.
