4.2 Serial Communication
The PowerCore module does not have any serial transceivers directly on the board.
However, a serial interface may be incorporated into the board the PowerCore module is
mounted on. For example, the PowerCore Prototyping Board has RS-422 and RS-232
transceiver chips.
4.2.1 Serial Ports
There are six serial ports on the Rabbit 3000—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 the PowerCore module has been programmed
and is operating in the Run Mode.
Serial Port B is used to communicate with the serial flash on the PowerCore module, and
so is not available for any other applications.
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.
Serial Ports E and F can also be configured as HDLC serial ports. The IrDA protocol is
also supported in SDLC format by these two ports. Serial Port E can also be configured for
SDLC.
The three serial ports that support clocked serial communications, Serial Ports A, C, and
D, are suitable for interfacing with “SPI” devices.
4.2.2 Ethernet Port
Figure 7 shows the pinout for the RJ-45 Ethernet port (J2). Note that some Ethernet con-
nectors are numbered in reverse to the order used here.
ETHERNET

Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate a live Ethernet link
(DS2 green) and one to indicate Ethernet activity (DS1 yellow).
