9 HIGH-SPEED COUNTER INSTRUCTION
9.2 High-speed Current Value Transfer Instruction
9.2 High-speed Current Value Transfer Instruction
High-speed current value transfer of 16-bit data
HCMOV(P)
These instructions read and write (updates) special register for high-speed counter, pulse width measurement, PWM, and
positioning.

■Applicable devices
Processing details
These instructions transfer the data in the device specified by (s) to the device specified by (d). At this time, if the value of (n)
is K0, the value of (s) is not cleared. If the value of (n) is K1, the value of (s) is cleared to "0" after the transfer. The value is
cleared only for special devices supporting high-speed transfer.
When (s) is a device supporting high-speed transfer
• When the HCMOV instruction is executed, the latest value is acquired such as the current value of a high-
speed counter and transferred to (d).
When (d) is a device supporting high-speed transfer
• When the HCMOV instruction is executed, value such as the current value of a high-speed counter is
changed.
■Effect of HCMOV instruction
• By using both input interrupt and HCMOV instruction, the current value of a high-speed counter can be received at the
rising edge or falling edge of an external input.
• When HCMOV instruction is used just before a comparison instruction (CMP, ZCP or comparison contact instruction), the
latest value of the high-speed counter is used in comparison.
