B.4.4 Serial Communication
The Prototyping Board allows you to access five of the serial ports from the RCM4000
module. Table B-5 summarizes the configuration options. Note that Serial Ports E and F
can be used only with the RCM3400 Prototyping Board.
Serial Ports E and F may be used as serial ports, or the corresponding pins at header loca-
tion J2 may be used as parallel ports.
