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
