3.1
When the master has control of SCIO, a standby pulse
can be generated by holding SCIO high for T
this time, the 11XX will reset and return to Standby
mode. Subsequently, a high-to-low transition on SCIO
(the first low pulse of the header) will return the device
to the active state.
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. However, a period of T
observed after the end of the command and before the
beginning of the start header. After T

in order to begin the new command.

All operations must be preceded by a start header. The
start header consists of holding SCIO low for a period
of T
code. This code is used to synchronize the slave’s
internal clock period with the master’s clock period, so
accurate timing is very important.

If a command is terminated in any manner other than a
NoMAK/SAK combination, then the master must per-
form a standby pulse before beginning a new com-
mand, 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.
A standby pulse cannot be generated while the slave
has control of SCIO. In this situation, the master must
wait for the slave to finish transmitting and to release
SCIO before the pulse can be generated.
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.
When a standby pulse is not required (i.e., between
successive commands to the same device), a period of
T
and before the beginning of the start header.
Figure 3-2 shows the waveform for the start header,
including the required Acknowledge sequence at the
end of the byte.
