Serial Acknowledge
An ACK (Acknowledge), is a software convention used
to indicate a successful data transfer. The transmitting
device, either master or slave, releases the bus after
transmitting eight bits. During the ninth clock cycle, the
receiver pulls the SDA line LOW to acknowledge the
reception of the eight bits of data. See Figure 3.
The device responds with an ACK after recognition of a
START condition followed by a valid Slave Address
byte. A valid Slave Address byte must contain the
Device Type Identifier 0101, and the Device Address
bits matching the logic state of pins A2, A1, and A0.
See Figure 4.
If a write operation is selected, the device responds
with an ACK after the receipt of each subsequent
eight-bit word.
In the read mode, the device transmits eight bits of
data, releases the SDA line, and then monitors the line
for an ACK. The device continues transmitting data if
an ACK is detected. The device terminates further data
transmissions if an ACK is not detected. The master
must then issue a STOP condition to place the device
into a known state.
