After configuration, the pins of the SelectMAP port can be
used as additional user I/O. Alternatively, the port can be
retained to permit high-speed 8-bit readback.
Retention of the SelectMAP port is selectable on a
design-by-design basis when the bitstream is generated. If
retention is selected, PROHIBIT constraints are required to
prevent the SelectMAP-port pins from being used as user
I/O.
Table 9: SelectMAP Write Timing Characteristics
Write
Write operations send packets of configuration data into the
FPGA. The sequence of operations for a multi-cycle write
operation is shown below. Note that a configuration packet
can be split into many such sequences. The packet does
not have to complete within one assertion of CS, illustrated

Multiple Virtex FPGAs can be configured using the Select-
MAP mode, and be made to start-up simultaneously. To
configure multiple devices in this way, wire the individual
CCLK, Data, WRITE, and BUSY pins of all the devices in
parallel. The individual devices are loaded separately by
asserting the CS pin of each device in turn and writing the
appropriate data.
