Inverse Assembly Synchronization
When you press the Invasm key to begin inverse assembly of a trace, the
inverse assembler begins with the first displayed state in the trace list. This is
called synchronization. It looks at the status bits (STAT) and determines
the type of processor operation, which is then displayed under the STAT
label. If the operation is an opcode fetch, the inverse assembler uses the
information on the data bus to look up the corresponding opcode in a table,
which is displayed under the DATA label. If the operation is a data transfer,
the data and corresponding operation are displayed under the DATA label.
This continues for all subsequent states in the trace list.
