UBAMRH Bits 15–0—User Break Address Mask 31–16 (UBM31–UBM16): These bits
designate whether to mask any of the break address 31–16 bits (UBA31–UBA16) established
in the UBARH.

UBAMRL Bits 15–0—User Break Address Mask 15–0 (UBM15–UBM0): These bits
designate whether to mask any of the break address 15–0 bits (UBA15–UBA0) established in
the UBARL.
Bits 15 – 0: UBMn Description
0 Break address UBAn is included in the break conditions (initial value)

7.2.3 User Break Bus Cycle Register (UBBR)
User break bus cycle register (UBBR) is a 16-bit readable/writable register that selects from
among the following four break conditions:
1. CPU cycle/ DMAC/DTC cycle
2. Instruction fetch/data access
3. Read/write
4. Operand size (byte, word, longword)
Resets and hardware standbys initialize the UBBR to H'0000. It is not initialized in software
standby mode.
