Defines the mode of operation of the trigger-out function.
Section 4.1.3: Performance counters on page 243 defines the
length of trigger out pin pulses.
Value - Description
0b000: The trigger-out function is disabled and the DM_TROUT_N
pin is held high.
0b001: An active-low pulse is output each time a WPC (a CPU core
watchpoint) channel triggers, and the triggering channel has
.ACTION_TRIG_OUT set as one of its actions.
0b010: An active-low pulse is output each time a bus analyzer
channel triggers, and the triggering channel has
.ACTION_TRIG_OUT set as one of its actions.
0b100: The trigger-out pin is connected to the output of the WPC
chain-latch, WPC.CHAIN_0.
0b101: The trigger-out pin (DM_TROUT_N) is connected to the
output of the DM shared chain-latch, DM.CHAIN_0.
0b110: The trigger-out pin is connected to the stall-acknowledge
signal from the CPU core. If stall mode is selected, the
DM_TROUT_N signal goes low during the time that the CPU is
stalled when the capture buffer is full.
0b111: Undefined
