C INTERFACE
Communicating with this device is initiated by sending a valid address on the I
2
C bus. The address format (see FIgure 1) has 5 fixed bits and
two user-programmable bits followed by a 1-bit read/write value which determines the direction of the data transfer.

C Address Byte
Following the address and acknowledge bit are 8 data bits which, depending on the read/write bit in the address, will read data from or write
data to the non-volatile register. Data will be written to the register if the read/write bit is logic 0 and the WP input is logic 0. Data will be read
from the register if the bit is logic 1. The four high-order bits are latched outputs, while the four low order bits are multiplexed outputs (Figure 2).
NOTE:
1. To ensure data integrity, the non-volatile register must be internally write protected when V

2
C bus is powered down or V

component is dropped below normal operating levels.
