Single copy / Multi-page copy
The scanned data passes to the page memory after video processing in the
DIP block in the FCIP. After a page of data has been stored in the page mem-
ory, the data is sent to the MCB through the LIF block, and then to the LDDR.
This process is the same for multi-page copying.
