TABLE 5-1: COMMAND SUMMARY TABLE
Command
Result if Device Has Not Yet
Been Assigned an ID Byte
Result if Device Has Already Been
Assigned an ID Byte
Assign Address
command
Clear Address
command
Read or Write
command with
ID byte set to 00h
Read or Write
command with
ID byte set to xxh
(other than 00h)
Set Write-Protect
command with
ID byte set to 00h
Set Write Protection
command with
ID byte set to xxh
(other than 00h)
If device wins arbitration, then ID
byte will become xxh. If device
loses arbitration, then ID byte will
revert back to 00h.
Device will remain with ID byte set
to 00h.
Since the default ID byte for the
device is 00h, the device will
execute the command.
Device will acknowledge the
control byte, but it will not acknowl-
edge any further bytes and will not
respond to the command.
Since the default ID address for the
device is 00h, the device will
execute the command.
Device will acknowledge the
control byte, but it will not acknowl-
edge any further bytes and will not
respond to the command.
Device will not acknowledge command.
Device ID byte will revert back to 00h and will then
acknowledge Assign Address commands.
Device will acknowledge the control byte, but it will not
acknowledge any further bytes and will not respond to
the command.
If the device ID byte matches the ID byte in the command
(xxh), the device will execute the command. If the device
ID byte does not match the ID byte in the command, then
the device will acknowledge the control byte, but it will
not acknowledge any further bytes and will not respond
to the command.
Device will acknowledge the control byte, but it will not
acknowledge any further bytes and will not respond to
the command.
If the device ID byte matches the ID byte in the command
(xxh), the device will execute the command. If the device
ID byte does not match the ID byte in the command, then
the device will acknowledge the control byte, but it will
not acknowledge any further bytes and will not respond
to the command. Note: Once this command has been
executed successfully for a device, the device will no
longer acknowledge any part of this command again.
