3.6 Serial Programming Cable
The programming cable is used to connect the serial programming port of the Coyote 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 3000.
When the
header on the Coyote’s RabbitCore module, programs can be downloaded and debugged
over the serial interface.
The
the Coyote’s RabbitCore module with the Coyote operating in the Run Mode. This allows
the programming port to be used as a regular serial port.
3.6.1 Changing Between Program Mode and Run Mode
The Coyote is automatically in Program Mode when the
gramming cable is attached, and is automatically in Run Mode when no programming
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
the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the
programming cable’s
causing the Rabbit 3000 to operate in the Run Mode.
A program “runs” in either mode, but can only be downloaded and debugged when the
Coyote is in the Program Mode.
Refer to the
gramming port and the programming cable.
