*: The external I/O, counter I/O, interrupt input, pulse/PWM outputs use the same area by specifying the operation I/O operation mode (WRF070). See Chapter 8 for further information.

Note: The MICRO-EH does not support CPU link area (L/WL).

Note: B and W in the Size column represent bit and word (16 bits), respectively.
