S = Start
ACK = Acknowledge
AZ = AutoZero-Remain
T = Testing
I = Autoincrement
P = Stop
MAX CLOCK SPEED 500kbits/s
The transmitted data is automatically updated after each ACK. Transmission can be repeated without new
chip address.
7.2 Auto increment
) _{If bit I in the subaddress byte is set to "1", the autoincrement of the subaddress is enabled.}
