3.2.1.3 Programming Port
The CPU Card has a 10-pin programming header labeled J2. The programming port uses
the Rabbit 2000’s Serial Port A for communication. Dynamic C uses the programming
port to download and debug programs.
The programming port is also used for the following operations.
• Cold-boot the Rabbit 2000 on the RabbitCore module after a reset.
• Remotely download and debug a program over an Ethernet connection using the
• Fast copy designated portions of flash memory from one Rabbit-based board (the
Alternate Uses of the Serial 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 serial programming port may also be used as a serial port via the
the serial programming cable.
In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the serial programming port.
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 CMOS output.
The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the
onboard peripheral circuits on the Smart Star. The serial programming port can be used to
force a hard reset on the Smart Star by asserting the /RESET_IN signal.
