Master Parallel Mode
In Master Parallel mode, the lead FPGA directly addresses
an industry-standard byte-wide EPROM and accepts eight
data bits right before incrementing (or decrementing) the
address outputs.
The eight data bits are serialized in the lead FPGA, which
then presents the preamble data (and all data that over-
flows the lead device) on the DOUT pin. There is an inter-
nal delay of 1.5 CCLK periods, after the rising CCLK edge
that accepts a byte of data, and also changes the EPROM
address, until the falling CCLK edge that makes the LSB
(D0) of this byte appear at DOUT. This means that DOUT
changes on the falling CCLK edge, and the next device in
the daisy chain accepts data on the subsequent rising
CCLK edge.
