Configurable Watchdog
As no CPLD is available, the Watchdog must be used from the SoC. The WDOG features are listed below:
Configurable timeout counter with timeout periods from 0.5 to 128 seconds which, after timeout expiration,
result in the assertion of WDOG_RESET_B_DEB reset signal .
Time resolution of 0.5 seconds
Configurable timeout counter that can be programmed to run or stop during low-power modes
Programmable interrupt generation prior to timeout
The duration between interrupt and timeout events can be programmed from 0 to 127.5 seconds in steps of
0.5 seconds.
