OFFSET REGISTER
RS2, RS1, RS0 = 1, 1, 0; Power-On/Reset = 0x8000 (AD7796)/0x800000 (AD7797)
The analog input channel has an offset register that holds the offset calibration coefficient for the channel. This register is 16 bits wide on
the AD7796 and 24 bits wide on the AD7797, and its power-on/reset value is 0x8000(00). The offset register is used in conjunction with
the full-scale register to form a register pair. The power-on/reset value is automatically overwritten if an internal or system zero-scale
calibration is initiated by the user. The offset register is a read/write register. However, the AD7796/AD7797 must be in idle mode or
power-down mode when writing to this register.
FULL-SCALE REGISTER
RS2, RS1, RS0 = 1, 1, 1; Power-On/Reset = 0x5XXX (AD7796)/0x5XXX00 (AD7797)
The full-scale register is a 16-bit register on the AD7796 and a 24-bit register on the AD7797. The full-scale register holds the full-scale
calibration coefficient for the ADC. The full-scale register is a read/write register. However, when writing to the full-scale register, the
ADC must be placed in power-down mode or idle mode. The full-scale register is configured on power-on with the factory-calibrated
full-scale calibration coefficient. Therefore, every device has a different default coefficient. The default value is automatically overwritten
if a system full-scale calibration is initiated by the user, or if the full-scale register is written to.
