8. Data Communications
8.1. Overview
The S-7600A chip contains a on-board serial port for physical transports. The data format of the serial
port is fixed at 1 start bit (logic "0"), 8 data bits, 1 stop bit (logic "1") and no parity bits. The data bits are
sent out, least significant bit first. This data format is shown in Figure 8-1. Also included with the serial
port is a 16- byte Receive FIFO and 1-byte Send Buffer.
