Comparison Instructions
Section 3-7
remainder of the instruction line is skipped and execution moves to the next
instruction line.
3-7-2
Time Comparison Instructions (341 to 346)
Purpose
Time comparison instructions compare two BCD time values and create an
ON execution condition when the comparison condition is true.
The time comparison instructions are treated just like the LD, AND, and OR
instructions to control the execution of subsequent instructions.
These instructions are supported only by CS/CJ-series CPU Unit Ver. 2.0 or
later.
