To modify the timer counter value (the WCRR), the prescaler ratio (the WCLR[4:2] PTV bit field), delay configuration value (the WDLY[31:0] DLY_VALUE bit field), or the load value (the WLDR[31:0] TIMER_LOAD bit field), the watchdog timer must be disabled by using the start/stop sequence (the WSPR).
After a write access, the load register value and prescaler ratio registers are updated immediately, but new values are considered only after the next consecutive counter overflow or after a new trigger command (the WTGR).
