Making Bit Settings for 4X Registers
You can only set 4X register bits using ladder logic. This section describes the layout for the registers and defines
the bits. Ladder logic examples are provided in chapter 4, “Programming.”
The first 4X register controls channel enabling and multiplexing. The following table shows the bit settings for
this register.
