Breakpoint Unit description
Figure 9-7.
The Breakpoint unit consists of the units shown in Figure 9-7. The PC Breakpoint Unit (PBU)
handles the program counter breakpoints. The PBU can have up to 6 PC breakpoint modules
that can match on a single PC. Two modules can be combined to give a match on a range of PC
values, thus up to three ranges can be defined. The PBU is configured with registers Breakpoint
/ Watchpoint Control (BWC) and Breakpoint / Watchpoint Address (BWA) 0A, 0B, 1A, 1B, 2A,
and 2B.
The Data Breakpoint Unit handles data breakpoints. The data breakpoints can be configured
with the BWC / BWA / BWD 3A and 3B registers.
