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
signal WD_RETRIG for the specified amount of time (see Figure 6 for WD_RETRIG (GPIO8)
line). The module has activate the WD_RETRIG signal by toggling the GPIO8 module output
within the specified time period. Otherwise the watchdog will reset the module. If enabled, each
GPIO8 toggling resets the timer to its configured value. Note that for this feature to work,
GPIO8 has to be available and enabled, and its direction must be set to output. Please refer to
Section 8.3.1.11, Section 8.4 and Section 8.5 for details on how to configure GPIO directions.
If configured as WD_RETRIG signal, GPIO8 cannot be used for any other purpose.
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).
