4.2 Serial Communication
The RCM4100 series board does not have any serial driver or receiver chips directly on
the board. However, an Ethernet or other serial interface may be incorporated on the board
the RCM4100 is mounted on. For example, the Prototyping Board has an RS-232 trans-
ceiver chip.
4.2.1 Serial Ports
There are six serial ports designated as Serial Ports A, B, C, D, E, and F. All six serial
ports can operate in an asynchronous mode up to the baud rate of the system clock divided
by 8. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where
an additional bit is sent to mark the first byte of a message, is also supported.
Serial Port A is normally used as a programming port, but may be used either as an asyn-
chronous or as a clocked serial port once application development has been completed and
the RCM4100 is operating in the Run Mode.
Serial Port B is shared by the RCM4100 module’s A/D converter, and is set up as a
clocked serial port. Since this serial port is set up for synchronous serial communication
on the RCM4100 model, you will lose the A/D converter’s functionality if you try to use
the serial port in the asynchronous mode. Serial Port B is available without any restrictions
on the RCM4110 and the RCM4120.
Serial Ports C and D can also be operated in the clocked serial mode. In this mode, a clock
line synchronously clocks the data in or out. Either of the two communicating devices can
supply the clock. Note that PD2 and PD0 provide the SCLKC and SCLKD outputs auto-
matically when Serial Ports C and D are set up as clocked serial ports.
Serial Ports E and F can also be configured as SDLC/HDLC serial ports. The IrDA proto-
col is also supported in SDLC format by these two ports. Serial Ports E and F must be con-
figured before they can be used. The sample program IOCONFIG_SWITCHECHO.C in the
Dynamic C SAMPLES\RCM4100\SERIAL folder shows how to configure Serial Ports E
and F.
