Intellicom (OP6600/OP6700)
3.2.3 Programming Port
The Intellicom has a 10-pin programming header labeled J4. The programming port uses
the Rabbit 2000’s serial port A for communication. The programming port uses the Rabbit
2000’s Serial Port A for communication. Dynamic C uses the programming port to down-
load and debug programs.
The programming port is also used for the following operations.
Cold-boot the Rabbit 2000 on the Intellicom after a reset.
Remotely download and debug a program over an Ethernet connection using the
RabbitLink EG2110.
Fast copy designated portions of flash memory from one Rabbit-based board (the
master) to another (the slave) using the Rabbit Cloning Board.
Alternate Uses of the Programming Port
All three clocked Serial Port A signals are available as
a synchronous serial port
an asynchronous serial port, with the clock line usable as a general CMOS input
The programming port may also be used as a serial port via the DIAG connector on the
programming cable.
In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the programming port header.
The two startup mode pins determine what happens after a reset—the Rabbit 2000 is
either cold-booted or the program begins executing at address 0x0000.
The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is
present. The status output has three different programmable functions:
1. It can be driven low on the first op code fetch cycle.
2. It can be driven low during an interrupt acknowledge cycle.
3. It can also serve as a general-purpose output.
The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the Intel-
licom onboard peripheral circuits.
Refer to the Rabbit 2000 Microprocessor User’s Manual for more information.
