This file describes the Watchdog Driver for all boards. A watchdog is a hardware device that will reset the board if not touched in a specific way at a regular interval. It is a simple, yet important, part of many embedded systems.
#define WATCHDOG_DRIVER_TABLE_ENTRY { Watchdog_initialize, NULL, NULL, NULL, NULL, Watchdog_control } |
This macro defines the watchdog device driver entry points.

Watchdog Driver Initialization.
This method initializes the watchdog hardware device. The device should be initialized as DISABLED since BSP initialization may take longer than the timeout period for the watchdog.
[in] | major | is the watchdog device major number |
[in] | minor | is the watchdog device minor number |
[in] | arguments | points to device driver arguments |
