4.2.3 LRC CHK (checksum)

LRC (Longitudinal Redundancy Check) is calculated by summing up the Hex values from ADR1 to last data character then finding the 2’s-complement negation of the sum.

Example: Read the content of register at address 0401H. 01H+03H+04H+01H+00+01H = 0AH.

The 2’s-complement of 0AH: F6H
