MOST (Maximum Outstanding Split Transactions): Three outstanding split transactions
are supported. Changing the value of this field decreases the maximum number of outstanding
split transactions:
Table 52: MOST Encoding
MMRBC (Maximum Memory Read Byte Count): This field sets the maximum byte count
the device uses when initiating a read sequence with one of the burst memory commands:
Table 53: MMRBC Encoding
ERO (Enable Relaxed Ordering): The Tsi148 does not support relaxed ordering. When this
field is read, the value is always zero.
DPERE (Data Parity Recovery Enable): When this bit is set and the device is in PCI-X
mode, the Tsi148 does not assert SERR_ when the master data parity error bit is set. When
this bit is clear and the device is in PCI-X mode, the Tsi148 asserts SERR_ when the master
data parity error bit is set.
NCAPP (Next Capabilities Pointer): This field points to the next item in the Capabilities
List. A zero indicates that this is the final item in the list.
CAPID (Capabilities ID): This field defines this item in the capabilities list as a PCI-X
register set. When this field is read, the value is always 0x07.
