Probe Adapter Circuit Description
The TMS 600 support uses a 144 pin EIAJ QFP test clip that interfaces between
the probe adapter and the microcontroller on the SUT.
The probe adapter has a jumper to select between the multiplexed and demulti-
plexed modes of operation.
The probe adapter uses the 74FCT162260AT 12-bit tri-port bus exchanger to
switch the address lines between Port0 and Port1. The probe adapter uses the
74FCT162244ET 16-bit buffer to buffer the other signal lines between the
microcontroller and the logic analyzer.
Replacing Signal Leads
Information on basic operations describes how to replace signal leads (individual
channel and clock probes).
