19 BUILT-IN I/O FUNCTION
19.1 High-speed Counter Function
Special registers for individual channels
This section only lists the devices for high-speed counter CH1. The devices for high-speed counter CH2 and subsequent
counters have the same operation as CH1.
: High-speed transfer capable (special register is immediately updated)
: Normal transfer capable (special register is updated in END processing)
: Transfer not possible (read-only)
Always use DHCMOV (32-bit instruction) for devices that use 2 words. When the HCMOV instruction (16-bit
instruction) is used, it operates the same as the normal MOV instruction.
