4.2.3 Programming Port
The PowerCore module’s programming port is accessed using header J2 or when pro-
gramming with a RabbitLink EG2110 through the Ethernet jack. The programming port
uses the Rabbit 3000’s Serial Port A for communication. Dynamic C uses the program-
ming port to download and debug programs.
The programming port is also used for the following operations.
• Cold-boot the Rabbit 3000 on the PowerCore 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 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
programming cable.
In addition to Serial Port A, the Rabbit 3000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the programming port.
The two startup mode pins determine what happens after a reset—the Rabbit 3000 is
either cold-booted or the program begins executing at address 0x0000. These two
SMODE pins can be used as general inputs once the cold boot is complete.
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 3000 and the
PowerCore module’s onboard peripheral circuits.
