Instruction
When use the built-in high speed counter of K80S, the HSC instruction should be used. The instruction format of HSC is as
following;
When the value of operation mode (D4999), PV or SV is not proper, the instruction error flag (F110) turns on and the HSC
instruction is not executed.

Remark
The U/D and PR input of sequence program must be programmed with dummy input even they are set as external
input. When the PR and/or U/D is set as external input, the input conditions of sequence program is ignored.
