Interface Pin Descriptions
The interface pins for the Serial/JTAG/SPI, SelectMAP, and adapter ports are described in Table 5, Table 6, and Table 7,
respectively.

Configuration Reset. This pin is used to force a reconfiguration of
the target FPGA(s). It should be connected to the PROG_B pin of the
target FPGA for a single-device system, or to the PROG_B pin of all
FPGAs in parallel in a daisy-chain configuration.

Configuration Clock. FPGAs load one configuration bit per CCLK
cycle in slave-serial mode. CCLK should be connected to the CCLK
pin on the target FPGA for a single-device configuration, or to the
CCLK pin of all FPGAs in parallel in a daisy-chain configuration.
Configuration Done. This pin indicates to MultiPRO tool that target
FPGAs have received the entire configuration bitstream. It should be
connected to the Done pin on all FPGAs in parallel for daisy-chained
configurations. Additional CCLK cycles are issued following the positive
transition of Done to insure that the configuration process is complete.
Configuration Data Input. This is the serial input data stream for
target FPGAs. It should be connected to the DIN pin of the target
FPGA in a single-device system, or to the DIN pin of the first FPGA
in a daisy-chain configuration.

Configuration Initialize. This pin indicates that configuration
memory is being cleared. It should be connected to the INIT_B pin of

all FPGAs in parallel in a daisy-chain configuration.
