VARIABLE LENGTH DELAY BITS
z
1-LINE (262144-BIT) DELAY
In read cycles, an output data is read at the (first) rising edge of RCK start the cycle. In write cycles, an input data is written
at the (second) rising edge of WCK end the cycle. So 1-line delay can be made easily according to the control method of
the following figure.
