VARIABLE-LENGTH DELAY BITS
• 1-line (1152-bit) delay
A write input data is written into memory at the second rise edge of WCK in the cycle, and a read output data is output from
memory at the first rise edge of RCK in the cycle, so that 1-line delay can be made easily.
• n-bit delay 1
(Making a reset at a cycle corresponding to delay length)
