Enabled or disabled; when enabled, the Target FIFO
interface will not transfer the MSB of the Target
address to the FPGA application, if it matches the
value of the previous transferred address. For dual-
port, the MSB will cover bits [64:32], whereas for
quad-port, the MSB represents bits [64:17]. If dis-
abled, the FPGA application will receive the address
covering the decoded BAR space.
Normal (16) or extended (32): The number of wait-
states to insert on Target reads until valid data is
recognized in the Target read data FIFOs. If no data
is detected, the Target will disconnect. Note that
only normal initial latency complies with PCI Specifi-
cation 2.2, Section 3.5.1.1. Extended latency may
be specified in proprietary systems where additional
clocks are required to return the first data word.
