I/O Configuration Block and DQS Configuration Block
The I/O configuration block and the DQS configuration block are shift registers that
you can use to dynamically change the settings of various device configuration bits.
The shift registers power-up low. Every I/O pin contains one I/O configuration
register, while every DQS pin contains one DQS configuration block in addition to the
I/O configuration register.
DQS configuration block circuitry.
