Calibration words are a composite oftwo independent bytes for each
channel. Enter calibration data in signed magnitude binary only. The
most significant bit in each byte is the sign bit; set for negative, reset
for positive.
Use the high byte (bits 10-17) for offset correction, the low byte (bits
00-07) for gain correction for each channel. Use word 20 for channel
1 thru word 27 for channel 8.
Refer to Chapter 7 for calibration procedures.
Word 28 Auto-calibration request word - used to automatically calibrate
selected channels and save the calibration constants in EEPROM.
