 Operation description
• Perform high-speed counter control which corresponds to the control code designated by "S".
• This instruction is used when high-speed counter performs below operation.
① Software reset, ② count is disabled, ③ External input makes reset input invalid, ④ When
the control executed by high-speed counter instruction F166 - F167 is canceled, clear target
value is interrupted.
• Once the control code is written, it will maintain till next writing.
• Control code written via F0 (MV) instruction is also saved to control code monitoring area
when written in special register DT90052. Only lower 8 bits are written.
 Precautions for programming
• The setting which is reset input invalid will become valid only when system register is used
to allocate reset input.
• The external reset input setting can be used to switch the reset input (X6 or X7) allocated to
