root int anaInEERd(unsigned int channel, unsigned int opmode,
unsigned int gaincode);
DESCRIPTION
Reads the calibration constants, gain, and offset for an input based on their designated
position in the flash memory, and places them into global tables _adcCalibS,
_adcCalibD, and _adcCalibM for analog inputs. 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.
