WATCHDOG

Modules§

  • ctrl
    Watchdog control
    The rst_wdsel register determines which subsystems are reset when the watchdog is triggered.
    The watchdog can be triggered in software.
  • load
    Load the watchdog timer. The maximum setting is 0xffffff which corresponds to 0xffffff / 2 ticks before triggering a watchdog reset (see errata RP2040-E1).
  • reason
    Logs the reason for the last reset. Both bits are zero for the case of a hardware reset.
  • scratch0
    Scratch register. Information persists through soft reset of the chip.
  • scratch1
    Scratch register. Information persists through soft reset of the chip.
  • scratch2
    Scratch register. Information persists through soft reset of the chip.
  • scratch3
    Scratch register. Information persists through soft reset of the chip.
  • scratch4
    Scratch register. Information persists through soft reset of the chip.
  • scratch5
    Scratch register. Information persists through soft reset of the chip.
  • scratch6
    Scratch register. Information persists through soft reset of the chip.
  • scratch7
    Scratch register. Information persists through soft reset of the chip.
  • tick
    Controls the tick generator
