Set Conditional Memory-Access Breakpoint
constant
is an expression. The value is 16 bits unless address is an N mode address, in
which case the value will be 32 bits.
ALL
For the description of this option, see Set Unconditional Memory-Access Breakpoint on
page 4-24.
Considerations
•
For information about setting an unconditional memory-access breakpoint, see
Considerations on page 4-25.
•
Change access is not allowed with conditional memory-access breakpoint.
Examples
099,01,00012-BM L2, W, R0 5 & 11 <> 0
099,01,00012-BM UC.2, 4+3, W, L+2 > 5
099,01,00012-BM UL.1, 20I, R, R5=0
099,01,00012-BM $sp+#44, w, $a1 <> 0x80020004
For more examples of setting conditional memory-access breakpoints, see
Appendix F, Sample Debug Sessions.
> break if the variable is greater than constant. This operator does a
signed comparison.
= break if the variable is equal to constant.
# | <> break if the variable is not equal to constant.
