Peripheral Watchdog[edit | edit source]

Description[edit | edit source]

The Watchdog interfaces available on ETRA SoM are based on STM32MP1 SoC.

The Watchdog portssupports the following standards and features:

  • Two independent watchdogs (IWDG1 and IWDG2) dedicated to MPU
    • 12-bit down-counter and 8-bit prescaler
    • Dual voltage domain, thus enabling operation in low-power modes
    • Independent 32 kHz internal RC clock that operate in Stop and Standby modes
  • One window watchdog (WWDG1) dedicated to the MCU
    • Programmable free-running 7-bit downcounter
    • Conditional reset
    • Early wakeup interrupt
    • can be frozen in debug mode
  • The MPU can receive an interrupt if the WWDG1 generates a reset
