Overview

Structs used by the driver.

Note

This is an example show how to instantiate WatchDog with watchdog_instance_t,
watchdog_heartbeat_t, and watchdog_hwreg_t.

  #define WDG_0 ((watchdog_hwreg_t *)SYSTEM_WATCHDOG_CTRL)
  
*watchdog_instance_t wdg_0 = {
    // Hardware Register Map
    .hwreg          = WDG_0,
    // Enable counter 0 to trigger first (interrupt)
    // Enable counter 1 to trigger the hardware reset of the SoC (Handled outside the SoC)
    .enable         = {0x1U, 0x1U},
    .prescaler      = WATCHDOG_PRESCALER_CYCLE_PER_MS-1,
    // The counter Limit 0 -> Set Limit Value for counter 0
    // The counter Limit 1 -> Set Limit Value for counter 1
    .counterLimit   = {WATCHDOG_TIMEOUT_MS, 2*WATCHDOG_TIMEOUT_MS},
    // Heartbeat Config: WDG_TIMER_CLEAR, WDG_TIMER_UNLOCK , WDG_TIMER_LOCK
    .heartbeat      = 0x0U,
 };
 
  watchdog_applyConfig(&wdg_0);
