WDTCALH—Watchdog Timer Calibration High Byte
The WDTCALH and WDTCALL bytes, when loaded into the watchdog timer reload reg-
isters result in a one second timeout at room temperature and 3.3V supply voltage. To use
the Watch-Dog Timer calibration, user code must load WDTU with 0x00, WDTH with
WDTCALH and WDTL with WDTCALL.
