Recording Modes

When you define an event, you can specify the recording mode that the Bus State

Analyzer uses to collect data. This section explains how the different modes work.

Continuous: All Cycles

After execution begins, the trace buffer begins storing data from the first cycle. This

continues until execution arrives at a breakpoint, or until you halt execution.

Continuous: Events Only

After execution begins, the trace buffer begins storing data when data matches an event

definition. This continues until execution arrives at a breakpoint, or until you halt

execution.

Counted: All Cycles

After execution begins, the trace buffer begins storing data after the specified number of

cycles from first cycle. A breakpoint can stop storage before the analyzer stores the

specified number of cycles, as can halting execution.

Counted: Events Only

After execution begins, the trace buffer begins storing data that matches an event

definition for the specified number of cycles. A breakpoint can stop storage before the

analyzer stores the specified number of cycles; as can halting execution.

A+B+C+D

After execution begins, the trace buffer begins storing data from the first cycle run. This

continues through the occurrence of event A, B, C, or D (whichever is enabled); data

storage ends after the specified number of post-trigger cycles.

A+B -> C+D

After execution begins, the trace buffer begins storing data from the first cycle. This

continues through the occurrence of two events: A or B, followed by C or D. Data storage

ends after the specified number of post-trigger cycles.

If you select this mode, you must enable event A, event B, or both. You must enable event

C, event D, or both. Otherwise, the bus state analyzer cannot be triggered.

A -> B -> C !D

After execution begins, the trace buffer begins storing data from all cycles. This continues

through the occurrence of three events, A, B, and C, in order, if event D does not occur. (If
