MTBDWT_TBCTRL field descriptions
Field Description
31–28
NUMCOMP
Number of Comparators
This read-only field specifies the number of comparators in the MTB_DWT. This implementation includes
two registers.
27–2
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
1
ACOMP1
Action based on Comparator 1 match
When the MTBDWT_FCT1[MATCHED] is set, it indicates MTBDWT_COMP1 address compare has
triggered and the trace buffer's recording state is changed.
0 Trigger TSTOP based on the assertion of MTBDWT_FCT1[MATCHED].
1 Trigger TSTART based on the assertion of MTBDWT_FCT1[MATCHED].
0
ACOMP0
Action based on Comparator 0 match
When the MTBDWT_FCT0[MATCHED] is set, it indicates MTBDWT_COMP0 address compare has
triggered and the trace buffer's recording state is changed. The assertion of MTBDWT_FCT0[MATCHED]
is caused by the following conditions:
• Address match in MTBDWT_COMP0 when MTBDWT_FCT0[DATAVMATCH] = 0
• Data match in MTBDWT_COMP0 when MTBDWT_FCT0[DATAVMATCH, DATAVADDR0] = {1,0}
• Data match in MTBDWT_COMP0 and address match in MTBDWT_COMP1 when
MTBDWT_FCT0[DATAVMATCH, DATAVADDR0] = {1,1}
0 Trigger TSTOP based on the assertion of MTBDWT_FCT0[MATCHED].
1 Trigger TSTART based on the assertion of MTBDWT_FCT0[MATCHED].
