9.2 Calibration Word 2
The TTA<3:0> bits at memory location 2082h calibrate
the overtemperature shutdown threshold point. Firm-
ware must read these values and write them to the
TTACAL register for proper calibration.
The BGR<3:0> bits at memory location 2082h calibrate
the internal band gap. Firmware must read these
values and write them to the BGRCAL register for
proper calibration.
