Timer 256 points (0.01 s timer has only 0 to 63)
Counter 256 points (The same area as the timer is used.)
(The same timer counter number cannot be used more
than once.)
*: 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.
