(Process) (Redundant)
• The RnCPU and RnENCPU with firmware version "17" or later support these instructions. (Use an engineering tool with version "1.020W" or later.)
These instructions perform addition of the data stored in the devices specified by (s) to (s)+(n)-1 and calculate the horizontal
parity, and stores the added data in the device specified by (d) and the horizontal parity in the device specified by (d)+1.
