Operation

HARD reset
Trace data in the debug module FIFO can be read via this port when
the FIFO is in “DM FIFO trace hold” mode or “circular DM FIFO”
mode.
Returns a DM FIFO data word when the FIFO is in “DM FIFO trace
hold” mode or “circular DM FIFO” mode (DM.TRCTL.DESTN = 0b00
or 0b11). When the trace message destination is the development
tool or target system trace buffer, reads have no effect on the DM
FIFO and return undefined data.
Section 1.9.3: DTRC messages on page 119 defines the format of
trace messages.
