Precautions on dedicated instructions

This section describes the precautions for the following instructions.
• ICFCNT1
• ICRCNT1
• ICPWM1
(1) Multiple instruction executions in one scan
The instruction may not be successfully processed if it is executed to the same channel more than one time in
one scan.
(2) Programs with single instruction execution
Programs do not normally processed if any of the instructions is executed in the program that is executed only
once, because the off status of the execution command cannot be detected. Use the instruction in a program,
such as a scan program, where the off status of an execution command can be detected.
(3) Instructions not requiring an execution command
The following instructions are executed even while the execution command is off, because they can be executed
at any time. Therefore, errors can occur even while an execution command is off.
