Table 9 lists the total number of bits required to configure
each device.
Slave-Serial Mode
In slave-serial mode, the FPGA receives configuration data
in bit-serial form from a serial PROM or other source of
serial configuration data. The serial bitstream must be set
up at the DIN input pin a short time before each rising edge
of an externally generated CCLK.
For more detailed information on serial PROMs see the
PROM data sheet at ds026.pdf.
Multiple FPGAs can be daisy-chained for configuration from
a single source. After a particular FPGA has been config-
ured, the data for the next device is routed to the DOUT pin.
Data on the DOUT pin changes on the rising edge of CCLK.
The change of DOUT on the rising edge of CCLK differs
from previous families but does not cause a problem for
mixed configuration chains. This change was made to
improve serial configuration rates for Virtex and Virtex-E
only chains.
Figure 13 shows a full master/slave system. A Virtex-E
device in slave-serial mode should be connected as shown
in the right-most device.
Slave-serial mode is selected by applying <111> or <011>
to the mode pins (M2, M1, M0). A weak pull-up on the mode
pins makes slave-serial the default mode if the pins are left
unconnected. However, it is recommended to drive the con-
figuration

slave-serial mode programming switching characteristics.
Table 10 provides more detail about the characteristics
shown in Figure 14. Configuration must be delayed until the
INIT pins of all daisy-chained FPGAs are High.
