9.0 DEVICE CALIBRATION
Read-only memory locations 2080h through 208Fh
contain factory calibration data. Refer to Section 18.0
“Flash Program Memory Control” for information on
how to read from these memory locations.
9.1 Calibration Word 1
The DOV<3:0> bits at memory location 2080h set the
offset calibration for the output voltage remote sense
differential amplifier. Firmware must read these values
and write them to the DOVCAL register for proper
calibration.
The FCAL<6:0> bits at memory location 2080h set the
internal oscillator calibration. Firmware must read
these values and write them to the OSCCAL register
for proper calibration.
