Watchdog control The rst_wdsel register determines which subsystems are reset when the watchdog is triggered. The watchdog can be triggered in software.
Logs the reason for the last reset. Both bits are zero for the case of a hardware reset. Additionally, as of RP2350, a debugger warm reset of either core (SYSRESETREQ or hartreset) will also clear the watchdog reason register, so that software loaded under the debugger following a watchdog timeout will not continue to see the timeout condition.
