Received Split Completion Error Message
The LSISAS1068 sets this bit upon receipt of a split
completion message if the split completion error attribute
bit is set. Write a one (1) to this bit to clear it.
Designed Maximum Cumulative Read Size
These read only bits indicate a number greater than or
equal to the maximum cumulative size of all outstanding
burst memory read transactions for the LSISAS1068 PCI
device. The PCI function must report the smallest value
that correctly indicates its capability. The LSISAS1068
reports 0b100 in this field to indicate a designed
maximum cumulative read size of 16 Kbytes.
Designed Maximum Outstanding
Split Transactions
These read only bits indicate a number greater than or
equal to the maximum number of all outstanding split
transactions for the LSISAS1068 PCI device. The PCI
function must report the smallest value that correctly
indicates its capability. The LSISAS1068 reports 0b110 in
this field to indicate that the designed maximum number
of outstanding split transactions is sixteen.
Designed Maximum Memory Read
Byte Count
These read only bits indicate a number greater than or
equal to the maximum byte count for the LSISAS1068
device. The PCI function uses this count to initiate a
sequence with one of the burst memory read commands.
The PCI function must report the smallest value that
correctly indicates its capability. The LSISAS1068 reports
0b10 in this field to indicate that the designed maximum
memory read bytes count is 2048.
