The transmitted data is automatically updated after each ACK.
Transmission can be repeated without new chipaddress.
SOFTWARE SPECIFICATION
Interface Protocol
The interface protocol comprises:
A start condition (s)
A chip address byte,(the LSB bit determines
read/write transmission)
A subaddress byte.
A sequence of data (N-bytes + acknowledge)
A stop condition (P)
