RabbitCore RCM3200
4.2 Serial Communication
The RCM3200 board does not have an RS-232 or an RS-485 transceiver directly on the
board. However, an RS-232 or RS-485 interface may be incorporated on the board the
RCM3200 is mounted on. For example, the Prototyping Board has a standard RS-232
transceiver 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 Ports
A, B, 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 sup-
ply the clock. When the Rabbit 3000 provides the clock, the baud rate can be up to 80% of
the system clock frequency divided by 128, or 276,250 bps for a 44.2 MHz clock speed.
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 Port A is available only on the programming port.
