Defines the chain-latch used in conjunction with
ACTION_CHAIN_ALTER. Only certain chain-latches can be
controlled by each watchpoint. See Section 4.1.4: Chain

16 1 — Trigger out enable RW
Operation
Enables or disables generation of a trigger out message for the
WP channel. The effect of this on the DM_TROUT_N pin is
determined by the programming of the DM.TRCTL register. See
Section 1.8.10: DM.TRCTL (trace/trigger register) on page 97.
Value - Description
0: The DM_TROUT_N pin is unaffected by hits on this WP
channel.
1: If DM.TRCTL.DM_TRIG_OUT_MODE == 0b010, then a
low-going pulse is produced on the DM_TROUT_N pin each
time a hit occurs on this WP channel (see Section
1.8.10: DM.TRCTL (trace/trigger register) on page 97). If
DM.TRCTL.DM_TRIG_OUT_MODE has any other value, hits on
this WP channel have no effect on the DM_TROUT_N pin.
