DS2465

DeepCover Secure Authenticator with

SHA-256 Coprocessor and 1-Wire Master Function

I C Communication Examples (continued)

Case B: 1-Wire Idle (1WB = 0), Busy Polling Until the 1-Wire Command is Completed

Repeat until the

1WB bit has

AD,0

60h

1WSB A <byte> A

changed to 0.

Sr AD,1 A <byte> A <byte> A\

When 1WB has changed from 1 to 0, the 1-Wire Master Status register holds the valid result of the 1-Wire Single

Bit command.

Case C: 1-Wire Busy (1WB = 1)

AD,0

60h

1WSB A\ P

The master should stop and restart as soon as the DS2465 does not acknowledge the command code.

1-Wire Write Byte, e.g., to Send a Command Code to the 1-Wire Line

Case A: 1-Wire idle (1WB = 0), No Busy Polling

AD,0

60h

1WWB

33h

(Idle)

33h is the valid 1-Wire ROM function command for Read ROM. The idle time is needed for the 1-Wire function to

complete. There is no data read back from the 1-Wire line with this command.

Case B: 1-Wire Idle (1WB = 0), Busy Polling Until the 1-Wire Command is Completed.

Repeat until the

1WB bit has

AD,0 A 60h A 1WWB A 33h A

changed to 0.

Sr AD,1 A <byte> A <byte> A\

When 1WB has changed from 1 to 0, the 1-Wire Write Byte command is completed.

Case C: 1-Wire Busy (1WB = 1)

AD,0 A 60h A 1WWB A\ P

The master should stop and restart as soon as the DS2465 does not acknowledge the command code.

1-Wire Read Byte, e.g., to Read a Byte from the 1-Wire Line

Case A: 1-Wire Idle (1WB = 0), No Busy Polling, Set read address before Idle Time

AD,0

60h

1WRB

Sr AD,0

62h

(Idle)

S AD,1 A <byte> A\ P

The read address is set to the 1-Wire Read Data register while the 1-Wire Read Byte command is still in progress.

Then, after the 1-Wire function is completed, the device is accessed to read the data byte that was obtained from

the 1-Wire line.
