Note:
Register description
Control register (CR)
Read/Write
Reset Value: 0111 1111 (7Fh)
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
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).
These bits contain the decremented value. A reset is produced when it rolls over from 40h to
3Fh (T6 becomes cleared).
