B.4.6 Serial Communication
The Prototyping Board allows you to access up to three of the serial ports from the
RCM3900/RCM3910. Table B-2 summarizes the configuration options.
Ordinarily, Serial Port D must be configured either to allow J7 to be used as a RabbitNet
port or to allow J11 to be used as a serial interface for the SF1000 series serial flash. When
other RabbitCore modules supplied with this Prototyping Board in their Development Kit
are plugged into the Prototyping Board, PD2 is configured in software to enable the RS-422
transceiver for the RabbitNet SPI interface. PD2 is not brought out from the RCM3900/
RCM3910. Serial Port D may be used as a serial port via the Prototyping Board when the
RCM3900/RCM3910 is installed with PC0 and PC1 to a serial transceiver of your own in
the prototyping area.
