Layout and Pin Reference
All serial ports are configured as data terminal equipment (DTE). Both the send and
receive registers of each port have a 16-byte FIFO. All serial ports have
16C550-compatible UARTs. The RS-232 transceivers have charge pumps to generate
the plus and minus voltages so the PCM-C418 only re5V to operate.
Each port is setup to provide internal diagnostics such as loopback and echo mode on
the data stream. An independent, software-programmable baud rate generator is
