Table 1092
DTSA being less than, greater than, or equal to DTEA.
Programmed values
DTSA < DTEA
DTSA < DTEA
DTSA > DTEA
DTSA = DTEA
Note: DTSA must be less than DTEA in order to guarantee correct Data Write/Read Traces. Data
Trace ranges are inclusive of the DTSA and DTEA addresses for Range Control settings
indicating "within range," and are exclusive of the DTSA and DTEA addresses for Range
Control settings indicating "outside of range."
Accesses that meet the range and access type qualifiers will cause assertion of a
watchpoint output for Ranges 1, 2, and 3. There are three dedicated watchpoint outputs,
one for each DTSA/DTEA sets 1, 2, and 3. Range 4 does not provide a watchpoint output.
Note that when DTC
prefetches) are monitored, and thus these range watchpoints differ from the IACx
watchpoint outputs, which are not asserted for instructions that are not executed (i.e. when
the instruction prefetch is discarded).
