Source Destination Indicator — In Normal and Loop1 mode this bit indicates if the corresponding stored
address is a source or destination address. This bit has no meaning in Compressed Pure PC mode.
0 Source Address
1 Destination Address
Vector Indicator — In Normal and Loop1 mode this bit indicates if the corresponding stored address is a vector
address. Vector addresses are destination addresses, thus if CVA is set, then the corresponding CSD is also set.
This bit has no meaning in Compressed Pure PC mode.
0 Non-Vector Destination Address
1 Vector Destination Address
Program Counter bit 17— In Normal and Loop1 mode this bit corresponds to program counter bit 17.
Program Counter bit 16— In Normal and Loop1 mode this bit corresponds to program counter bit 16.
Trace Buffer Organization (Compressed Pure PC mode)
Configured for end aligned triggering in compressed PurePC mode, then
after rollover it is possible that the oldest base address is overwritten. In this
case all entries between the pointer and the next base address have lost their
base address following rollover. For example in
rollover has occurred, Line 1, PC1, is overwritten with a new entry. Thus the
entries on Lines 2 and 3 have lost their base address. For reconstruction of
program flow the first base address following the pointer must be used, in
the example, Line 4. The pointer points to the oldest entry, Line 2.
