TRANSACTION SEQUENCE

The sequence for accessing the DS1065 via the 1-Wire port is as follows:

Initialization

Function Command

Transaction/Data

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

DS1065. The presence pulse lets the bus master know that the DS1065 is present and is ready to operate.

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 DS1065’s DIV register.

Read DIV Register [A1H]

This command allows the bus master to read the DS1065’s DIV register.
