To communicate with a remote device, the host controller
(master) sends the slave address and listens for a response
from the slave. This response is referred to as an acknowl-
edge bit (ACK). If a slave on the bus is addressed correctly,
it Acknowledges (ACKs) the master by driving the SDA bus
low. If the address doesn't match a device's slave address, it
Not-acknowledges (NACKs) the master by letting SDA be
pulled High. ACKs also occur on the bus when data is being
transmitted. When the master is writing data, the slave ACKs
after every data byte is successfully received. When the mas-
ter is reading data, the master ACKs after every data byte is
received to let the slave know it wants to receive another data
byte. When the master wants to stop reading, it NACKs after
the last data byte and creates a stop condition on the bus. All
communication on the bus begins with either a Start condition
or a Repeated Start condition. All communication on the bus
ends with a Stop condition. A READ is shown in
and a WRITE is shown in
If the Serial Bus is not required, the three pins may be left
open (NC).
