A serial interface comprises a clock line, a request line, a ready line, a master-to-slave data line, and a slave-to-master data line. A master device transmits a clock signal to a slave device over the clock line. In a first transaction, the master device sends a master transmission request signal to the slave device over the request line; in response, the slave device sends a slave transmission accept signal over the ready line, which causes the master device to transmit binary data to the slave device over the master-to-slave data line. In a second transaction, the slave device sends a slave transmission request signal over the ready line; in response, the master device sends a master transmission accept signal over the request line, which causes the slave device to transmit binary data to the master device over the slave-to-master data line. In at least one of the transactions, the master and slave devices transmit binary data at the same time as each other.
A data-exchange system comprising a master device, a slave device, and a synchronous serial connection therebetween,
A master device configured to receive a slave-to-master binary message from a slave device, over a synchronous serial connection, containing data and message-length information relating to the length of the slave-to-master binary message, and, at the same time, to transmit a master-to-slave binary message, containing data, to the slave device over the synchronous serial connection;
