The CQM1-CPU44-EV1 has two dedicated ports (CN1 and CN2) for receiving
grey codes from an absolute-type rotary encoder.
These two ports can be used to carry out absolute-type high-speed counter
interrupts. Grey codes input to the ports can be received at a computation speed
of up to 4 kHz, and processing can be executed according to that value.
