Operation State Diagram
The diagram below shows the state diagram for basic
operation of the 24LCS61/62. This diagram shows pos-
sible states and operational flow once power is applied
to the device. Table 5-1 summarizes operation of each
command for the assigned and unassigned states.

Assign Address Command:

Assign Address Command:
Device loses Arbitration
(ID byte not assigned yet)
(ID byte has been assigned)
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
If device wins arbitration, then ID
byte will become xxh. If device
loses arbitration, then ID byte will
revert back to 00h.
Device will not acknowledge command.
Clear Address
command
Device will remain with ID byte set
to 00h.
Device ID byte will revert back to 00h and will then
acknowledge Assign Address commands.
Read or Write
command with
ID byte set to 00h
Since the default ID byte for the
device is 00h, the device will exe-
cute the command.
Device will acknowledge the control byte, but it will not
acknowledge any further bytes and will not respond to
the command.
Read or Write
command with
ID byte set to xxh
(other than 00h)
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.
Set Write Protect
command with
ID byte set to 00h
Since the default ID address for the
device is 00h, the device will exe-
cute the command.
Device will acknowledge the control byte, but it will not
acknowledge any further bytes and will not respond to
the command.
Set Write Protection
command with
ID byte set to xxh
(other than 00h)
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 exe-
cuted successfully for a device, the device will no longer
acknowledge any part of this command again.
