Operation
When read

HARD reset
Enables or disables generation of a trace message for the WP
channel (see Section 1.8.5: IA watchpoint trace modes on
page 92). The trace information generated varies according to
the WP channel. Section 1.6: WP channel matching on page 66
defines the terms used below.
Trace for the OA WP channels can be further controlled using
the DM.WP_OAX_ACTION:OA_MATCH field and the
DM.OA_MATCH_* registers (see Section 1.12.3: Data match
registers on page 147).
Trace is generated as described in Section 1.8.5: on page 92,
according to the mode specified:
Value - Description
0b00: trace generation disabled
0b01: trace generation disabled

applies for IA watchpoints, undefined effects occur if this is
programmed for non-IA channels.
0b11: trace generation enabled - multi trace mode
