Note:
Register description
Control register (WDGCR)
Reset value: 0111 1111 (7Fh)
Bit 7 = WDGA Activation bit
This bit is not used if the hardware watchdog option is enabled by option byte.
Bits 6:0 = T[6:0] 7-bit timer (MSB to LSB)
Table 34.
Address
(Hex.)
0033h
WDGA
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
These bits contain the decremented value. A reset is produced when it rolls over from
40h to 3Fh (T6 becomes cleared).
