Programming Model
Table 5-9 describes DBR fields.
Table 5-10 describes DBMR fields.
The DBR supports both aligned and misaligned references. Table 5-11 shows relationships
between processor address, access size, and location within the 32-bit data bus.
5.4.6 Program Counter Breakpoint/Mask Registers
The PC breakpoint register (PBR) defines an instruction address for use as part of the
trigger. This register’s contents are compared with the processor’s program counter register

Data breakpoint value. Contains the value to be compared with the data value from the processor’s
local bus as a breakpoint trigger.
Data breakpoint mask. The 32-bit mask for the data breakpoint trigger. Clearing a DBR bit allows
the corresponding DBR bit to be compared to the appropriate bit of the processor’s local data bus.
Setting a DBMR bit causes that bit to be ignored.
