4.3 Programming Cable
A special programming cable is used to connect the PowerCore module’s programming
port to a serial COM port on the PC that hosts Dynamic C. The programming cable has a
small circuit board in the cable that converts the RS-232 voltage levels used by the PC
serial port to the CMOS voltage levels used by the Rabbit 3000. An additional adapter and
software is available so that a PC USB port can be used instead of a serial port.
When the
connector on the programming cable is connected to header J2 on the
PROG
PowerCore module, programs can be downloaded and debugged over the serial interface.
The
connector of the programming cable may be used on header J2 of the PowerCore
DIAG
module with the PowerCore module operating in the Run Mode. This allows the program-
ming port to be used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The PowerCore module is automatically in Program Mode when the
connector on
PROG
the programming cable is attached, and is automatically in Run Mode when no program-
ming cable is attached. When the Rabbit 3000 is reset, the operating mode is determined
by the status of the SMODE pins. When the programming cable’s
connector is
PROG
attached, the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode.
When the programming cable’s
PROG
connector is not attached, the SMODE pins are
pulled low, causing the Rabbit 3000 to operate in the Run Mode.
