10.2 FNC 21 – SUB / Subtraction

Program example

1. Difference between SUB instruction and DEC instruction caused by a program for 

subtracting "1"

"1" is subtracted from the contents of D0 every time X001 turns ON from OFF.
SUB[P] instruction is similar to DECP instruction described later except the contents shown in the table
below:

[D] SUB [P] instruction
