NOTE
The MC register is not available prior to Revision D of the MPC561 and is
not available in Revision B and earlier versions of the MPC563. Prior
revisions have only the default features.

QTST
Enables a factory test mode for structural testing of the queue. This bit can only be
written in factory test mode. When set, no trace messages are queued.
Users should always write this bit as a 0.
5
2
PTM
The Program Trace Mode (PTM) bit enables an enhanced method of program trace.
This mode allows program trace to work with the ISCTL bits of the ICTRL register set
to any value except 3. The value of 2 is recommended for optimal processor
performance. The drawback of this mode is direct branch messages are never
syncronizing so sync requests must be held until the next indirect branch.
0 Legacy Program Trace Mode
1 Enhanced Program Trace Mode
6
1
QFM
The Queue Flush Mode (QFM) bit selects if information in the queue is discarded or
transmitted at the time of an overrun. Discarding information allows trace to resume
quicker after an overrun, but makes it difficult to find the cause of the overrun.
0 Information in the queue is removed
1 Trace is stopped until the queue empties.
7
0
PTSM
The Program Trace Sync Mode (PTSM) indicates if the program trace messages
contain the I-CNT packet.
0 Program trace message do not contain the I-CNT packet.
1 Program trace message contain the I-CNT packet.
