9.3
Calibration Word 3
The BGR<4:0> bits at memory location 2082h calibrate
the band gap reference. Firmware must read these
values and copy into the BGRCAL Special Function
Register located in Bank 3 at 19Bh.
9.4
Calibration Word 4
The TTA<3:0> bits at memory location 2083h contain
the calibration bits for the factory-set overtemperature
threshold. Firmware must read these values and copy
into the TTACAL Special Function Register located in
Bank 3 at 19Ah.
