5.0
Communication is formatted using 8-bit bytes. All
bytes are transmitted with the Most Significant bit sent
first and the Least Significant bit sent last. Each bit is
transmitted immediately following the previous bit, with
no delay in between bits. An example is shown in
Figure 5-1.
FIGURE 5-1:
5.1
An Acknowledge routine occurs after each byte is
transmitted, including the start header. This routine
consists of two bits. The first bit is transmitted by the
master and the second bit is transmitted by the slave,
as shown in Figure 5-2.
5.1.1
The Master Acknowledge, or MAK, is signified by trans-
mitting a ‘
to be continued (i.e., more data will be sent).
Conversely, a Not Acknowledge, or NoMAK, is signified
by transmitting a ‘0’, as shown in Figure 5-3, and is
used to end the current command and initiate any
corresponding internal processing, if necessary.
A MAK must always be transmitted following the start
header. If a NoMAK is transmitted, device operation will
be undefined.
5.1.2
The Slave Acknowledge, or SAK, is also signified by
transmitting a ‘
the previous byte of data. Unlike the NoMAK, the
NoSAK is signified by the lack of a middle edge during
the bit period.
In order to avoid possible bus collision due to multiple
devices transmitting at the same time, no slave device
will respond with a SAK until a specific slave has been
selected. That is, a NoSAK will occur after each byte
that is transmitted before the end of the device address
(i.e., for 8-bit addressing, a NoSAK occurs after the
start header only, and for 12-bit addressing, a NoSAK
occurs after both the start header and the MSB of the
device address).

5.1.3
If a SAK is not received from the slave after any byte
(after a device has been selected), an error has
occurred. The master should then perform a standby
pulse and begin the desired command again.
