Programming watchpoints
To make a watchpoint unit cause watchpoints on data accesses:
1.
2.
3.
4.
5.
6.
7.
The above are examples of how to program the watchpoint register to generate
breakpoints and watchpoints. Many other ways of programming the registers are
possible. For instance, you can provide simple range breakpoints by setting one or more
of the address mask bits.
Program its address value register with the address of the data access to be
watchpointed.
Program the address mask register to
Program the data value register only if you require a data-dependent watchpoint,
that is, only if you need to match the actual data value read or written as well as
the address. If the data value is irrelevant, program the data mask register to
Program the control value register with nOPC = 1, nRW = 0 for a read, or nRW
= 1 for a write, MAS[1:0] with the value corresponding to the appropriate data
size.
Program the control mask register with nOPC = 0, nRW = 0, MAS[1:0] = 0 and
all other bits to 1. You can set nRW, or MAS[1:0] to 1 when both reads and
writes, or data size accesses are to be watchpointed respectively.
If you wish to make the distinction between User and non-User mode data
accesses, program the nTRANS bit in the control value and control mask
registers accordingly.
If required, program the EXTERN, RANGE, and CHAIN bits in the same way.
