WDTCALH—Watchdog Timer Calibration High Byte
The WDTCALH and WDTCALL bytes, when loaded into the Watchdog Timer reload
registers result in a one second timeout at room temperature and 3.3 V supply voltage. To
use the Watchdog 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
registers result in a one second timeout at room temperature and 3.3 V supply voltage. To
use the Watchdog Timer calibration, user code must load WDTU with 0x00, WDTH with
WDTCALH and WDTL with WDTCALL.
S_NUM—Serial Number Byte
The serial number is a unique four-byte binary value.
