watchdog_enable() function

Enable the watchdog By default the SDK assumes a 12MHz XOSC and sets the watchdog_start_tick appropriately. This method sets a marker in the watchdog scratch register 4 that is checked by watchdog_enable_caused_reboot. If the device is subsequently reset via a call to watchdog_reboot (including for example by dragging a UF2 onto the RPI-RP2), then this value will be cleared, and so watchdog_enable_caused_reboot will return false.

from watchdog.h:87

void watchdog_enable(uint32_t delay_ms, bool pause_on_debug);

Argument

Description

delay_ms

Number of milliseconds before watchdog will reboot without watchdog_update being called. Maximum of 8388, which is approximately 8.3 seconds

pause_on_debug

If the watchdog should be paused when the debugger is stepping through code

Notes

If watchdog_start_tick value does not give a 1MHz clock to the watchdog system, then the \p delay_ms parameter will not be in milliseconds. See the datasheet for more details.
