8.1.2 Communication with remote device stations
This section explains an overview of the communication between the master and
remote device stations.
In the communication with remote device stations, the signals for handshaking with
remote device stations (initial data request flag, error reset request flag, etc.) are
communicated using remote input RX and remote output RX. Numeric data (averaging
processing specification, digital output value, etc.) is communicated using remote
register RWw and remote register RWr.
