DS1085L
SLAVE ADDRESS
A control byte is the first byte received following the START condition from the master device. The
control byte consists of a 4-bit control code; for the DS1085L, this is set as 1011 binary for read and write
operations. The next three bits of the control byte are the device select bits (A2, A1, A0). The address bits
to which the DS1085L responds are factory set to 000, but can be altered by writing new values to the
ADDR register. After the new address is written, the DS1085L responds only to the new address bit
values. The master uses this to select which of eight devices are to be accessed. The set bits are in effect
the three least significant bits of the slave address. The last bit of the control byte (R/W) defines the
operation to be performed. When set to a 1, a read operation is selected; when set to a 0, a write operation
is selected. Following the START condition, the DS1085L monitors the SDA bus checking the device
type identifier being transmitted. Upon receiving the 1011 code and appropriate device select bits, the
slave device outputs an acknowledge signal on the SDA line.
