The DIFF<7:0> bits at memory location 2086h contain
the offset voltage information for the output voltage
difference amplifier. The value is an 8-bit two’s
complement number that represents the number of the
OVFCON counts needed to adjust for the differential
amplifier offset. This value can be used to completely
remove the differential amplifier offset.
For example, the offset of the differential amplifier is
measured to be +4.2 mV. Since one OVFCON count
equals 0.7 mV, this represents six counts of the
OVFCON register. Therefore the value stored at
location 2086h would be 0x06h, where clearing the
DIFF7 bit represents a positive number.
