WATCHDOG TIMER (Cont’d)
11.1.8 Register Description
CONTROL REGISTER (CR)
Read /Write
Reset Value: 0111 1111 (7F h)
Bit 7 = WDGA
Activation bit.
This bit is set by software and only cleared by
hardware after a reset. When WDGA = 1, the
watchdog can generate a reset.
0: Watchdog disabled
1: Watchdog enabled
Note: This bit is not used if the hardware watch-
dog option is enabled by option byte.
Bits 6:0 = T[6:0]
7-bit timer (MSB to LSB).
These bits contain the decremented value. A reset
is produced when it rolls over from 40h to 3Fh (T6
becomes cleared).
