REV. 1.2.15 1/14/02
After each byte is read, the pointer auto-increments to allow
multiple data byte transfers within one read cycle.
Preceding each slave write, there must be a start cycle.
Following the pointer byte there should be a stop cycle.
After the last read, there must be a stop cycle comprising
a LOW-to-HIGH transition of SDA while SCL is HIGH.
(see Figure 18, right waveform)
A repeated start signal occurs when the master device driv-
ing the serial interface generates a start signal without first
generating a stop signal to terminate the current communica-
tion. This is used to change the mode of communication
(read, write) between the slave and master without releasing
the serial interface lines.
Serial Interface Read/Write Examples
Examples below show how serial bus cycles can be linked
together for multiple register read and write access cycles.
For sequential register accesses, each ACK handshake ini-
tiates further SCL clock cycles from the master to transfer
the next data byte.
