TRANSACTION SEQUENCE
The sequence for accessing the DS1073 via the 1-Wire port is as follows:
INITIALIZATION
All transactions on the 1-Wire bus begin with an initialization sequence. The initialization sequence
consists of a reset pulse transmitted by the bus master followed by a presence pulse(s) transmitted by the
DS1073. The presence pulse lets the bus master know that the DS1073 is present and is ready to operate.
Figure 13
FUNCTION COMMANDS
Once the bus master has detected a presence, it can issue one of the four function commands. All
function commands are 8 bits long, and are written lsb first. A list of these commands follows:
Write DIV Register [01H]
This command allows the bus master to write to the DS1073’s DIV register.
