Bits Name Function
[31] STATUS

Single-shot status. This indicates whether any of the selected comparators have matched:

0Match has not occurred.
1Match has occurred at least once.

When programming ETM-M33, if TRCSSCCR0.RST is 0, the STATUS bit must be explicitly written to 0 to enable this single-shot comparator control.

[30:4] - res0.
[3] PC

Indicates that the Single-shot comparator is sensitive to processor comparator inputs:

1Single-shot comparator is sensitive to processor comparator inputs.
[2] DV

Data value comparator support:

0Single-shot data value comparisons not supported.
[1] DA

Data address comparator support:

0Single-shot data address comparisons not supported.
[0] INST

Instruction address comparator support:

0Single-shot instruction address comparisons not supported.
