I2C bus interface description
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)
Figure 30.
Interface protocol diagram
S = Start;
ACK = Acknowledge;
AZ = AutoZero-Remain;
T = Testing;
I = Auto increment;
P = Stop;
Max clock speed is 500 kbits/s.
The transmitted data is automatically updated after each ACK.
Transmission can be repeated without new chip address.
