Writes the calibration constants, gain, and offset for an input based from global tables

_adcCalibS

_adcCalibD

, and

_adcCalibM

to designated positions in the flash memory. Depending on the flash

size, the following macros can be used to identify the starting address for these locations.

ADC_CALIB_ADDRS, address start of single-ended analog input channels

ADC_CALIB_ADDRD, address start of differential analog input channels

ADC_CALIB_ADDRM, address start of milliamp analog input channels

NOTE: This function cannot be run in RAM.

PARAMETER

channel is the analog input channel number (0 to 7) corresponding to LN0_IN to LN7_IN.

opmode is the mode of operation:

SINGLE—single-ended input line

DIFF—differential input line

mAMP—milliamp input line
