SigmaQuad-II B4 SRAM DDR Write
The status of the Address Input, W, and R pins are sampled by the rising edges of K. W and R high causes chip disable. A low on
the Write Enable-bar pin, W, and a high on the Read Enable-bar pin, R, begins a write cycle. W is always ignored if the previous
command was a write command. Data is clocked in by the next rising edge of K, the rising edge of K after that, the next rising edge
of K, and finally by the next rising edge of K. and by the rising edge of the K that follows.
