High-speed Counter Function10-1010.3.2 [F1 DMV] Elapsed Value Write / Read InstructionWrites and reads the elapsed value of the high-speed counter.

Outline of operation (Setting elapsed value)• At the same time as writing the value to the elapsed value area of the high-speed counterwhich uses 32-bit data specified by [S], sets it in the elapsed value area of the high-speedcounter used within the system. Precautions during programming• Only F1 (DMV) instruction can perform the writing. The writing cannot be performed by otherhigh-level instructions such as transfer instruction F0 (MV) and arithmetic instructions.• Specify the memory area of [S] or [D] with the memory area number for the lower 16 bits.REFERENCE• For details of the allocations of I/O and flags, refer to "12.2.4 When UsingHigh-speed Counter Function".• For details of the FPΣ mode, refer to "11.
