Output Register Overview
In addition to the Input registers, there are four 16-bit registers that are sent to the
MMC120 each time the I/O drop is accessed. The registers contain commands and data:
Register Number Contents
4TTTTT + 0 Command –axis1
4TTTTT + 1 Data out axis 1
4TTTTT + 2 Command –axis2
4TTTTT + 3 Data out axis 2
The commands sent to the two axes are independent of each other.
Data should only be written to the module once per segment, otherwise new data
overwrites previous data. Only the last information placed in the output registers is
transferred to the module.
