Chapter 8 High-speed counter, PWM / Pulse train output and Analogue I/O

8.1.4 Input/Output Setting (Mode 10)

Mode 10 had been added since Ver. 01.13. I/O assignment of mode 10 is very flexible as follows.

Parameter setting is compatible with existing mode 0 to 3 except for WRF071. Operation of FUN command (FUN 140 - 150) is same for all the mode 0 to 10.
