Single-Channel 1-Wire Master
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
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
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)
The master should stop and restart as soon as the DS2482-100 does not acknowledge the command code.
1-Wire Write Byte (To Send a Command Code to the 1-Wire Line)
Case A: 1-Wire Idle (1WB = 0), No Busy Polling
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.
When 1WB has changed from 1 to 0, the 1-Wire Write Byte command is completed.
Case C: 1-Wire Busy (1WB = 1)
The master should stop and restart as soon as the DS2482-100 does not acknowledge the command code.
