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)

Auto Increment
If bit I in the subaddress byte is set to ”1”, the autoincrement of the subaddress is enabled.
