B.4.4.1 RS-232
RS-232 serial communication on header J4 on both Prototyping Boards is supported by an
RS-232 transceiver installed at U3. This transceiver provides the voltage output, slew rate,
and input voltage immunity required to meet the RS-232 serial communication protocol.
Basically, the chip translates the Rabbit 4000’s signals to RS-232 signal levels. Note that
the polarity is reversed in an RS-232 circuit so that a +3.3 V output becomes approxi-
mately -10 V and 0 V is output as +10 V. The RS-232 transceiver also provides the proper
line loading for reliable communication.
RS-232 can be used effectively at the maximum baud rate for distances of up to 15 m.
RS-232 flow control on an RS-232 port is initiated in software using the
trolOn
of the flow control lines are specified using a set of five macros.
Standard 3-wire RS-232 communication using Serial Ports C and D is illustrated in the
following sample code.

SERX_RTS_PORT—Data register for the parallel port that the RTS line is on (e.g., PCDR).
SERA_RTS_SHADOW—Shadow register for the RTS line's parallel port (e.g., PCDRShadow).
SERA_RTS_BIT—The bit number for the RTS line.
SERA_CTS_PORT—Data register for the parallel port that the CTS line is on (e.g., PCDRShadow).
SERA_CTS_BIT—The bit number for the CTS line.
