Input Data is clocked into the DI pin on the rising edge of the clock SK
Output data is clocked out on the falling edge of the SK clock.
The WC pin does not have any affect on the READ, WEN and WDS operations.
Between instructions, CS must be brought High for greater than the minimum of
t
CS
. If CS is maintained Low, the next instruction isn't detected.
