While writing to the DLPC operating in the I²C target configuration, the first byte following the start condition should be the DLPC device write address (34h). It is possible to change the device address to any other desired value using DLP Composer tool. The remaining bytes are sent as specified in the Chapter 16 below.

While reading from the DLPC in I²C target configuration, the first byte following the start condition should be DLPC device write address +1 (35h default) followed by header and opcode bytes as explained later in the document. All reads from DLPC via I²C interface starts with a write as explained above specifying the opcode for read. The host should then continue the I²C transaction with a Restart-Read followed by the number of bytes associated with the command and finally the Stop.
