Function: The watchdog timer is an 8-bit counter incremented by the input clock. It provides
a monitoring function that resets the IC internally when, due to system runaway or
other problem, the counter overflows before the counter value is rewritten.
Features: • The watchdog timer counter is incremented by an internal clock with a
frequency of ø/8192, and generates a reset signal (WRST) when the counter
• The overflow period can be set to a value between 1 and 256 times 8192/ø.
