Chapter 7 Debug Module (DBGV1) Block Description
7.4.2.5.8
In the inside range trigger mode, if the match condition for A and B happen on the same bus cycle, both
the A and B flags in DBGSC are set and a trigger occurs. If a match condition on only A or only B occurs
no flags are set. If TRGSEL = 1, the inside range is accurate only to word boundaries. If TRGSEL = 0, an
aligned word access which straddles the range boundary will cause a trigger only if the aligned address is
within the range.
7.4.2.5.9
In the outside range trigger mode, if the match condition for A or B is met, the corresponding flag in
DBGSC is set and a trigger occurs. If TRGSEL = 1, the outside range is accurate only to word boundaries.
If TRGSEL = 0, an aligned word access which straddles the range boundary will cause a trigger only if the
aligned address is outside the range.

The definitions of some of the control bits are incompatible with each other.

Read/write comparisons are not compatible with TRGSEL = 1. Therefore, RWAEN and RWBEN
are ignored.
Event-only trigger modes are always considered a begin-type trigger. See
“Storing with
Detail capture mode has priority over the event-only trigger/capture modes. Therefore, event-only
modes have no meaning in detail mode and their functions default to similar trigger modes.
