Setting Up the Support
This section provides information on how to set up the support. Information
covers the following topics:
H
Channel group definitions
H
Clocking options
H
Symbol table files
Remember that the information in this section is specific to the operations and
functions of the TMS 109A Socket 7 support on any Tektronix logic analyzer for
which it can be purchased. Information on basic operations describes general
tasks and functions.
Before you acquire and disassemble data, you need to load the support and
specify setups for clocking and triggering as described in the information on
basic operations. The support provides default values for each of these setups,
but you can change them as needed.
Channel Group Definitions
The software automatically defines channel groups for the support. The channel
groups for the Socket 7 support are Address, Data, Data_Lo, Control, DataSize,
Cache, and Misc.
Clocking Options
A special clocking program is loaded to the module every time you load the
SOCKET7_ 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 Socket 7 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 (CSM) generates one
master sample for each microprocessor bus cycle, no matter how many clock
cycles are contained in the bus cycle.
