CR#090~CR#093: Data written into/read from a DVP-FPMC QBuffer/Address of the data written
into/read from a DVP-FPMC QBuffer
[Description]
A QBuffer is designed for accessing several inconsecutive control registers by means of executing
TO/FROM once. PLC scan time can be reduced by decreasing the number of times TO/FROM is
executed. QBuffer access operation is described below.
For example, after the inconsecutive control register numbers CR#170, CR#171, CR#280, CR#289,
and CR#376 are written into the QBuffer address CR#91, DVP-FPMC will connect the data in CR#170,
CR#171, CR#280, CR#289, and CR#376 with CR#90 automatically. Users only need to access CR#90,
and the data in CR#170, CR#171, CR#280, CR#289, and CR#376 can be modified.
