Programming breakpoints
Hardware breakpoints on page B-45
Software breakpoints on page B-46
To make a watchpoint unit cause hardware breakpoints on instruction fetches:
1.
2.
3.
4.
5.
6.
7.
8.
Breakpoints are classified as hardware breakpoints or software breakpoints:
Program its address value register with the address of the instruction to be
breakpointed.
For an ARM-state breakpoint, program bits [1:0] of the address mask register to
11. For a breakpoint in Thumb state, program bits [1:0] of the address mask
register to 01.
Program the data value register only when you require a data-dependent
breakpoint, that is only when you need to match the actual instruction code
fetched as well as the address. If the data value is not required, program the data
mask register to
Program the control value register with nOPC = 0.
Program the control mask register with nOPC = 0.
When you need to make the distinction between User and non-User mode
instruction fetches, program the nTRANS value and mask bits appropriately.
If required, program the EXTERN, RANGE, and CHAIN bits in the same way.
Program the mask bits for all unused control values to 1.

Typically monitor the address value and can be set in any code, even in
code that is in ROM or code that is self-modifying.
Monitor a particular bit pattern being fetched from any address. One
EmbeddedICE watchpoint can therefore be used to support any number
of software breakpoints. Software breakpoints can normally be set only
in RAM because a special bit pattern chosen to cause a software
breakpoint has to replace the instruction.
