Debug Features and Watchpoint Facility
21.3.2.4
The trace buffer transaction mask register (TBTMR) shown in
types to monitor. Each bit in the TBTMR represents a transaction type on the selected interface. The
transaction associated with any particular bit depends on the interface being monitored as specified by
TBCR1[IFSEL]. Note that the transactions used for defining trace buffer events are the same as those
defined for watchpoint monitor events. Thus,
each interface. Setting a bit enables a hit when this transaction is matched (provided all other match criteria
are met and TBCR0[TMD] is clear).
Different interfaces support different transaction types, and the same bit may represent different
transaction types depending on the interface.

transaction associated with a bit depends on the interface being monitored. A value of 1 for a given mask bit
enables the matching of the transaction associated with that bit. These bits are meaningful only when
TBCR0[TMD]=0.
