Figure 26. Watchdog block diagram
Table 17.
Following a reset, the watchdog is disabled. Once activated it cannot be disabled, except by
a reset.
The T6 bit can be used to generate a software reset (the WDGA bit is set and the T6 bit is
cleared).
Software Watchdog option
If Software Watchdog is selected by option byte, the watchdog is disabled following a reset.
Once activated it cannot be disabled, except by a reset.
The T6 bit can be used to generate a software reset (the WDGA bit is set and the T6 bit is
cleared).
Hardware Watchdog option
If Hardware Watchdog is selected by option byte, the watchdog is always active and the
WDGA bit in the CR is not used.
Low power modes
WAIT instruction
No effect on Watchdog.
