The width of the Fastdata register is 1 bit. During a fast
data access, the Fastdata register is written and read
(i.e., a bit is shifted in and a bit is shifted out). During a
fast data access, the Fastdata register value shifted in
specifies whether the fast data access should be com-
pleted or not. The value shifted out is a flag that indi-
cates whether the fast data access was successful or
not (if completion was requested). The FASTDATA
access is used for efficient block transfers between the
DMSEG segment (on the probe) and target memory
(on the processor). An “upload” is defined as a
sequence that the processor loads from target memory
and stores to the DMSEG segment. A “download” is a
sequence of processor loads from the DMSEG seg-
ment and stores to target memory. The “Fastdata area”
specifies the legal range of DMSEG segment
addresses (0xFF20.0000-0xFF20.000F) that can be
used for uploads and downloads. The Data and Fast-
data registers (selected with the FASTDATA instruction)
allow efficient completion of pending Fastdata area
accesses.
During Fastdata uploads and downloads, the proces-
sor will stall on accesses to the Fastdata area. The
PrAcc (processor access pending bit) will be 1 indicat-
ing the probe is required to complete the access. Both
upload and download accesses are attempted by shift-
ing in a zero SPrAcc value (to request access comple-
tion) and shifting out SPrAcc to see if the attempt will be
successful (i.e., there was an access pending and a
legal Fastdata area address was used).
Downloads will also shift in the data to be used to
satisfy the load from the DMSEG segment Fastdata
area, while uploads will shift out the data being stored
to the DMSEG segment Fastdata area.
As noted above, two conditions must be true for the
Fastdata access to succeed. These are:
• PrAcc must be 1 (i.e., there must be a pending
• The Fastdata operation must use a valid Fastdata
