8-3. Consecutive register • data writing
Continuous data transmission after transmission of initially-set address data of register • data writing sequence enables
writing of data in the consecutive register • data area. In this case, the register • address increases by one address from
the initially-set address of the sequence and continues increasing till the "Stop" condition (P) is generated.
8-4. Consecutive register • data reading
When the master returns ACK (0 data) after reading of the initial register • address • data of read sequence, the register
• address increases by one address, enabling consecutive reading of data corresponding to each register address. If the
master does not return ACK (0 data), the register address does not increase.
