STOP (P) condition by transitioning SDA from low to
high while SCL is high. The bus is then free for another
transmission.
Bit Transfer
One data bit is transferred during each clock pulse
(Figure 4). The data on SDA must remain stable while
SCL is high.
Acknowledge
The acknowledge bit is a clocked 9th bit (Figure 5),
which the recipient uses to handshake receipt of each
byte of data. Thus, each byte transferred effectively
requires 9 bits. The master generates the 9th clock
pulse, and the recipient pulls down SDA during the
acknowledge clock pulse, so the SDA line is stable low
during the high period of the clock pulse. When the
master is transmitting to the MAX7347/MAX7348/
MAX7349, the MAX7347/MAX7348/MAX7349 generate
the acknowledge bit because the MAX7347/MAX7348/
MAX7349 are the recipients. When the MAX7347/
MAX7348/MAX7349 are transmitting to the master, the
master generates the acknowledge bit because the
master is the recipient.
