6.3.5 Instructions used with High-speed Counter Function
High-speed counter control instruction (F0)
• This instruction is used for counter operations such as software reset and count disable.
• Specify this instruction together with the special data register DT90052.
• Once this instruction is executed, the settings will remain until this instruction is executed again.
Operations that can be performed with this instruction
• Counter software reset (bit0)
• Counting operation enable/disable (bit1)
• Hardware reset enable/disable (bit2)
• Clear high-speed counter instructions F166 to F176
• Clear target value match interrupt
Example: Performing a software reset
In case of CH0
In the above program, the reset is performed in step

count is now ready for operation. If it is only reset,
counting will not be performed.
In case of CH1
