Some ACTION bits are available in DM.WP_BRX_FILTER:
ACTION_TRACE/TRACE_TYPE Is implicit - there is no ACTION_TRACE bit in
DM.WP_BRX_FILTER. Thus background trace messages are always generated for the
BR channel when it triggers.
TRACE_TYPE/ENABLE_TRACE_TIMESTAMP See Table 44: BR watchpoint trace message
on page 129.
ACTION_TRIG_OUT: Supported.
