The watchpoint monitor address mask register (WMAMR) shown in
address in the WMAR.

21.3.1.4
The watchpoint monitor transaction mask register (WMTMR), shown in
transaction types to monitor. WMTMR allows users to qualify watchpoint events specifically with any
combination of transaction types. As shown in
transaction types; one for each interface. Setting a bit enables watchpoint monitoring for the corresponding
transaction types.
Because the supported transaction types vary by interface, the type designated by a WMTMR field also
depends on the interface specified by WMCR1[IFSEL].

address bit. These bits only mask the address bits generated by the hardware, but do not affect the bits
specified in WMAR. A bit that is masked from the comparison should be set to 0 in WMAR.
The transaction associated with any particular bit may be different depending 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 WMCR0[TMD]=0.
