Both writes must occur in the order listed before the timeout, but any number of instructions can
be executed between the two writes. However, writing any value other than 0x5555 or 0xAAAA
to WSR resets the servicing sequence, requiring both values to be written to keep the watchdog
timer from causing a reset.
