WATCHDOG
Modules§
- Watchdog control
The rst_wdsel register determines which subsystems are reset when the watchdog is triggered.
The watchdog can be triggered in software. - Load the watchdog timer. The maximum setting is 0xffffff which corresponds to 0xffffff / 2 ticks before triggering a watchdog reset (see errata RP2040-E1).
- Logs the reason for the last reset. Both bits are zero for the case of a hardware reset.
- Scratch register. Information persists through soft reset of the chip.
- Scratch register. Information persists through soft reset of the chip.
- Scratch register. Information persists through soft reset of the chip.
