S = START condition.
SLAVE ADDRESS = 1000 100X.
ACK = acknowledge, generated by the slave.
SUBADDRESS = subaddress byte, see Table 1.
DATA = data byte, see Table 1.
P = STOP condition.
X = read/write control bit.
X = 0, order to write (the circuit is slave receiver).
X = 1, order to read (the circuit is slave transmitter).
If more than 1 byte of DATA is transmitted, then auto-increment of the subaddress is performed.
