6.1

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)

t(s Max clock speed is 500 kbits/s.

c The transmitted data is automatically updated after each ACK.
