User’s Manual 51
Reads the calibration constants, gain, and offset for an input based on their designated position in the
simulated EEPROM area of the flash memory, and places them into global tables
_adcCalibS ,
_adcCalibD , and _adcCalibM for analog inputs. The constants are stored in the top 2K of the user
block in a reserved memory area. 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 ADC_IN0 to ADC_IN7.
opmode is the mode of operation:
SINGLE—single-ended input line
DIFF—differential input line
mAMP—milliamp input line

unsigned int opmode, unsigned int gaincode);
