Display Data Channel Interfaces (DDC)
Random address read:
The master performs a
dummy write to load the data address into the
pointer LSB. Then the master sends a RESTART condition followed by a read Device Address (RW
= 1).
Sequential address read:
This mode is similar to the current and random address reads, except
that the master DOES acknowledge the data byte for the DDC2B Interface to output the next byte in
sequence. To terminate the read operation the master must NOT acknowledge the last data byte
and must generate a STOP condition. The data output are issued from consecutive memory
addresses.
End of communication
: Upon a detection of NACK or STOP conditions at the end of a read
transfer, the bit ENDCF is set and an interrupt is generated if ENDCE is set.
