4.3 Programming Cable
The programming cable is used to connect the programming port of the RCM4300 to a PC
serial COM port. The programming cable converts the RS-232 voltage levels used by the
PC serial port to the CMOS voltage levels used by the Rabbit 4000.
When the PROG connector on the programming cable is connected to the programming
port on the RCM4300, programs can be downloaded and debugged over the serial interface.
4.3.1 Changing Between Program Mode and Run Mode
The RCM4300 is automatically in Program Mode when the PROG connector on the pro-
gramming cable is attached, and is automatically in Run Mode when no programming
cable is attached. When the Rabbit 4000 is reset, the operating mode is determined by the
state of the SMODE pins. When the programming cable’s PROG connector is attached,
both the SMODE pins are pulled high, placing the Rabbit 4000 in the Program Mode.
When the programming cable’s PROG connector is not attached, the SMODE0 pin is
pulled low and the SMODE1 pin is high so that the Rabbit 4000 powers up in the clocked
serial bootstrap mode to load the program from the serial flash when the RCM4300 is
operating in the Run Mode.
