Section 12 Watchdog Timer
12.2.2
TCSR is an 8-bit readable and writable *
and clock source.
Bit
Initial value
Read/Write
Bits 7 to 5 are initialized to 0 by a reset and in standby mode. Bits 2 to 0 are initialized to 0 by a
reset. In software standby mode bits 2 to 0 are not initialized, but retain their previous values.
Notes: 1. TCSR differs from other registers in being more difficult to write. For details see
Bit 7—Overflow Flag (OVF): This status flag indicates that the timer counter has overflowed
from H'FF to H'00.
