MMDS0508 Target Interface

• 64 hardware instruction breakpoints over the 64-kilobyte memory map

• A personality file for each EM. (Each personality file defines a memory-map.)

• Latch-up resistant design (47-Ω series resistor on I/O connections to the target

system) to make power-up sequencing unimportant.

• Built-in bus state analyzer that includes:

• 8K x 64 real-time trace buffer

– Four hardware triggers, for controlling real-time bus analysis and to

provide breakpoints

– Nine triggering modes

– Display of real-time trace data as raw data, disassembled instructions, raw

data and disassembled instructions, or assembly-language source code

– As many as 8190 pre- or post-trigger points

– Trace buffer that can be filled as you single-stepping through user software

– 16-bit time tag, or an optional 24-bit time tag that sacrifices eight logic

clips

– Eight software selections for the time tag clock source, permitting wide

time variance between analyzer events

– 16 general-purpose logic clips, five of which can be used to trigger the bus

state analyzer sequencer

• Four software-selectable internally generated oscillator clock sources

• Built-in power supply with 85 to 264 VAC input

• RS-232 operation speeds as high as 57600 baud

• Compact size: 15.38 inches (390.6 mm) deep, 10.19 inches (258.83 mm) wide, and

2.75 inches (69.85 mm) high. The station module weighs 6.0 pounds (2.72 kg).

For connection instructions, configuration instructions, and other related information,

see the installation section of this hardware addendum. For similar information with

regard to EMs, see the corresponding EM user's manual.

1.3 System Components

The MMDS components include:

• Station module: the MMDS enclosure, containing the platform board and the

internal power supply. The access panel in the enclosure top lets you insert an EM

easily.
