9.4 Communication Processing for Transparent
Communication

9.4.1 Connection Processing Procedure

Transmission processing
The ET-LAN unit sends data through the communication circuit by writing it to the transmission buffer of
the shared memory and then executing the transmission request.
Reception processing
When the ET-LAN unit receives data from the communication circuit, the reception notified signal goes
on. If a reception request is executed while this signal is on, the received data is stored in the receive
buffer of the shared memory. Data is read from the receive buffer at the timing at which the reception
complete signal goes on.
