How Data is Acquired
This part of this chapter explains how the module acquires 80C167 signals using
the TMS 600 software and probe adapter. This part also provides additional
information on microcontroller signals accessible on or not accessible on the
probe adapter, and on extra probe channels available for you to use for additional
connections.
A special clocking program is loaded to the module every time you load the
80C167 support. This special clocking is called Custom.
With Custom clocking, the module logs in signals from multiple groups of
channels at different times as they become valid on the 80C167 bus. The module
then sends all the logged-in signals to the trigger machine and to the memory of
the module for storage.
In Custom clocking, the module clocking state machine generates one master
sample for each microcontroller bus cycle, no matter how many clock cycles are
contained in the bus cycle.
