8.3.1.4 UART Reset

This command configures a module reset, if no UART activity from the module was observed

for the specified amount of time - RST_UART. The module has to be active on the RXD0 signal

within the specified time period; otherwise the watchdog will reset the module.

Changing this configuration disables the watchdog. The feature becomes active, if the watch-

dog is enabled again, and after the MIN_START_TIME has passed.

For normal operation, this value should be set to a value greater than 10 minutes (

600000).

8.3.1.5 GPIO Reset

This command configures a module reset, if no activity from the module was observed on the

internal signal WD_RETRIG for the specified amount of time. The module has to be active on

the WD_RETRIG signal by toggling the GPIO22 module output within the specified time period.

Otherwise the watchdog will reset the module. If enabled, each GPIO22 toggling resets the tim-

er to its configured value.

Changing this configuration disables the watchdog. The feature becomes active, if the watch-

dog is enabled again, and after the MIN_START_TIME has passed.

For normal operation, this value should be set to a value greater than 10 minutes (

600000).
