Maxim Integrated
DS2483
Single-Channel 1-Wire Master
with Adjustable Timing and Sleep Mode
I2C Communication Examples (continued)
1-Wire Single Bit (To Generate a Single Time Slot on the 1-Wire Line)
Case A: 1-Wire Idle (1WB = 0), No Busy Polling
S
AD,0
A
1WSB
A
<byte>
P
(Idle)
S
AD,1
A
<byte>
A\
P
The idle time is needed for the 1-Wire function to complete. Then access the device in read mode to get the result
from the 1-Wire Single Bit command.
Case B: 1-Wire Idle (1WB = 0), Busy Polling Until the 1-Wire Command is Completed
S
AD,0
A
1WSB
A
<byte>
Sr
AD,1
AA
<byte>
A\
P
Repeat until the 1WB bit
has changed to 0.
When 1WB has changed from 1 to 0, the Status register holds the valid result of the 1-Wire Single Bit command.
Case C: 1-Wire Busy (1WB = 1)
S
AD,0
A
1WSB
A\
P
The master should stop and restart as soon as the DS2483 does not acknowledge the command code.
1-Wire Write Byte (To Send a Command Code or Data Byte to the 1-Wire Line)
Case A: 1-Wire Idle (1WB = 0), No Busy Polling
S
AD,0
A
1WWB
A
33h
A
P
(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.
S
AD,0
A
1WWB
A
33h

AD,1A
A
Sr
<byte>
A\
P
Repeat until the 1WB bit
has changed to 0.
When 1WB has changed from 1 to 0, the 1-Wire Write Byte command is completed.
Case C: 1-Wire Busy (1WB = 1)
S
AD,0
A
1WWB
A\
P
The master should stop and restart as soon as the DS2483 does not acknowledge the command code.
