BLL QDR SRAM input clock: This clock pair registers data
inputs on the rising edge of C and C#. All synchronous inputs
must meet setup and hold times around the clock rising
edges.
BLL QDR SRAM output clock: This clock pair times the control
outputs to the rising edge of K, and times the address and
data outputs to the rising edge of K and K#.
BLL QDR SRAM address outputs.
