Watchdog Timer Calibration Data

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.

WDTCALL—Watchdog Timer Calibration Low 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 watchdog timer calibration, user code must load WDTU with 0x00, WDTH with

WDTCALH and WDTL with WDTCALL.
