11AAXXX/11LCXXX

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.

3.0

3.1

BUS CHARACTERISTICS

Standby Pulse

When the master has control of SCIO, a standby pulse

can be generated by holding SCIO high for TSTBY. At

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.

Note: After a POR/BOR event occurs, a low-

to-high transition on SCIO must be gen-

erated before proceeding with communi-

cation, including a standby pulse.

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.

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 TSS must be

observed after the end of the command and before the

beginning of the start header. After TSS, the start

header (including THDR low pulse) can be transmitted

in order to begin the new command.

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.

Note 1: After a POR/BOR event, a low-to-high transition on SCIO is required to occur before the first

standby pulse.

When a standby pulse is not required (i.e., between

successive commands to the same device), a period of

3.2

Start Data Transfer

All operations must be preceded by a start header. The

start header consists of holding SCIO low for a period

of THDR, followed by transmitting an 8-bit ‘01010101’

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.

TSS must be observed after the end of the command

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.
