Communication The RCM3305 RCM3315 does not have any serial transceivers directly on the board However a serial interface may be incorporated into the board the RCM3305 RCM3315 is mounted on For example the Prototyping Board has RS 232 and RS 485 transceiver chips 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 the RCM3305 RCM3315 has been programmed and is operating in the Run Mode Serial Port B is used to communicate with the serial flash on the RCM3305 RCM3315 and is not available for other use 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 30 RabbitCore RCM3305 RCM3315 4 2 2 Ethernet Port Figure 7 shows the pinout for the RJ 45 Ethernet port J2 Note that some Ethernet con nectors are num
