Figure 7-4 Structure of Trace Control Table
①
Execution/stop
Used to set trace execution or stop.
0: Stop tracing
1: Continue tracing until the trace condition is met.
2: Continue tracing until the trace condition is met or until an error occurs.
When power is recovered or the resetting condition is cleared, a 2 is set. If an error is detected
or the trace condition is satisfied, tracing is stopped and a 0 is set.
②
Trace target address
Used to set the starting address of the condition trace target area.
③
Mask data
Set mask data for conditional tracing. Of the data bits, only the bit(s) set to 0 are masked off.
④
Comparison data
Set comparison data for conditional tracing. The comparison data is compared with the result
obtained by ANDing the trace target address in
②
and the mask data. If a match is found, the
condition holds.
⑤
Pointer
Used to point to the case in which the next trace data is to be stored. The newest trace data is
stored in pointer 1 (for 0, pointer 255).
