4.3 Programming Cable
The programming cable is used to connect the programming port of the RCM4000 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 RCM4000, programs can be downloaded and debugged over the serial interface.
The
DIAG
connector of the programming cable may be used on header J1 of the RCM4000
with the RCM4000 operating in the Run Mode. This allows the programming port to be
used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The RCM4000 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
status of the SMODE pins. When the programming cable’s
connector is attached,
PROG
the SMODE pins are pulled high, placing the Rabbit 4000 in the Program Mode. When the
programming cable’s
connector is not attached, the SMODE pins are pulled low,
PROG
causing the Rabbit 4000 to operate in the Run Mode.
