==Peripheral Watchdog ==
The Watchdog Timer (WDOG) protects against system failures by providing a method by which to escape from unexpected events or programming errors.

=== Description ===

'''By default, the Watchdog Timer of iMX6 SOC is internally used on AXEL Lite for the CPU-initiated software reset function.'''

For more details see the [[AXEL_Lite_SOM/AXEL_Lite_Hardware/Power_and_Reset/Reset_scheme_and_control_signals#Handling_CPU-initiated_software_reset|reset scheme and control signals]] section.

The Watchdog timer supports the following features:

* 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
* Power down counter with fixed timeout period of 16 seconds, which if not disabled after reset will assert WDOG_B signal low

===Pin mapping===

The Pin mapping is described in the [[AXEL Lite SOM/AXEL Lite Hardware/Pinout_Table | Pinout table section]]
