... Slave Address: This is the first byte received fol- lowing the start condition from the master device. The slave address consists of a 4-bit control code. For the DS3930, this is set as 1010 binary for read/write operations. The next bits of the slave address are the device address (A2–A0). The last bit of the slave address (R/W) defines the operation to be performed. When set to a ‘ ...
