6.4 Configuration Read and Write
PETrainer™ can automatically handle Configuration Read and Write TLP transactions:
• For a Configuration Read transaction, the Completion TLP contains the data
read from the internal Configuration Space according to specified register
address.
• For a Configuration Write transaction, the address for the internal
Configuration Space is updated with the data taken from Configuration Write
TLP, and Configuration Write Completion is returned.
You can specify the initial Configuration Space by editing the AddressSpace=Write
command directly in the script or by using the UI provided in the Generator toolbar.
The PETracer™ software provides a special editor for editing this file called the
Configuration Space Editor (see “Launching the Configuration Space Editor” on page 61).
