DIN
I
During slave serial or master serial conguration modes, DIN accepts serial conguration
data synchronous with CCLK. During parallel conguration modes, DIN is the D0 input. Dur-
ing conguration, a pull-up is enabled.
I/O After conguration, this pin is a user-programmable I/O pin.*
DOUT
O
During conguration, DOUT is the serial data output that can drive the DIN of daisy-chained
slave devices. Data out on DOUT changes on the rising edge of CCLK.
I/O After conguration, DOUT is a user-programmable I/O pin.*
TESTCFG
I
During conguration this pin should be held high, to allow conguration to occur. A pull up is
enabled during conguration.
I/O After conguration, TESTCFG is a user programmable I/O pin.*
* The FPGA States of Operation section contains more information on how to control these signals during start-up. The timing of DONE release
is controlled by one set of bit stream options, and the timing of the simultaneous release of all other conguration pins (and the activation of all
user I/Os) is controlled by a second set of options.
