WATCH
01Fh
Function
The WATCH register selects the watchdog timer value used during the reconfiguration processes. When RCFG[WDEN] enables
the watchdog timer, a count down timer begins. If the DUT software does not disable or restart the watchdog timer within the
specified limits, the system restarts.
Note that the watchdog timer is not dependent upon a reconfiguration sequence being active. While it is typically enabled along
with RCFG[GO] as part of a reconfiguration sequence; in fact, it is independent and can be enabled for any reason.
