Before communicating with a new device, a standby
pulse must be performed. This pulse signals to all
slave devices on the bus to enter Standby mode,
awaiting a new command to begin. The standby pulse
can also be used to prematurely terminate a
command.
The standby pulse consists of holding SCIO high for a
minimum of T
slave devices will be ready to receive a command.
Once a command is terminated satisfactorily (i.e., via
a NoMAK/SAK combination during the Acknowledge
sequence), performing a standby pulse is not required
to begin a new command as long as the device to be
selected is the same device selected during the previ-
ous command. In this case, a period of T
observed after the end of the command and before the
beginning of the start header. After T
header (including low pulse) can be transmitted in
order to begin the new command.
FIGURE 3-1:
Upon detection of the standby pulse, a slave device
will typically enter its lowest power state. The excep-
tion to this is when the slave device is executing an
internal process in the background. Examples include
an EEPROM performing a write cycle, or a tempera-
ture sensor carrying out a conversion.
If at any point during a command an error is detected
by the master, a standby pulse should be generated
and the command should be performed again.

If a command is terminated in any manner other than a
NoMAK/SAK combination, or if an invalid number of
data bytes has been sent (as specified by the com-
mand’s definition), then this is considered an error
condition and the master must perform a standby
pulse before beginning a new command, regardless of
which device is to be selected.
An example of two consecutive commands is shown in
Figure 3-1. Note that the device address is the same
for both commands, indicating that the same device is
being selected both times.
