Bit 2: Watchdog timer on (WDON)
Bit 2 enables watchdog timer operation.
Bit 2
WDON
0
1
Counting starts when this bit is set to 1, and stops when this bit is cleared to 0.
Bit 1: Bit 0 write inhibit (B0WI)
Bit 1 controls the writing of data to bit 0 in TCSRW.
Bit 1
B0WI
0
1
This bit is always read as 1. Data written to this bit is not stored.
Bit 0: Watchdog timer reset (WRST)
Bit 0 indicates that TCW has overflowed, generating an internal reset signal. The internal reset
signal generated by the overflow resets the entire chip. WRST is cleared to 0 by a reset from the
RES pin, or when software writes 0.
