Configuring the Command Converter

Motorola Preparation and Installation 2-13

2.2.1 Selecting the Command Converter Device Number

The command converter’s JG2 jumper group selects the device number that this particular

command converter will respond to when commanded by the user interface program.

Table 2-2 describes the device address select option:

Note: All command converters are factory configured for device address 0.

2.2.2 JTAG/OnCE Port Buffer V

In order to provide support for low voltage DSPs (5V-2.7V), an advanced low voltage

CMOS buffer exists between the DSP56002 controller and the target JTAG/OnCE

interface cable. This buffer has its V

pin connected to JG1, Pin 2. See Table 2-3 for

CMOS buffer V

configuration.

Note: The universal command converter is factory-configured for the JTAG/OnCE

buffers to be powered from the target system (JG1 2–3).

2.2.3 Command Converter Monitor Firmware Upgrades

The monitor code for the command converter, which is tailored for the target DSP family

in use, is provided with the ADS software. The code is downloaded automatically into the
