PRODUCTION DATA
Table 8-2 shows that the address byte is the first byte received following the START condition from the controller device. The first four bits (MSBs) of the address are factory preset to 1001. The next three bits of the address are controlled by the A0 pin. The A0 pin input can be connected to VDD, AGND, SCL, or SDA. The A0 pin is sampled during the first byte of each data frame to determine the address. The device latches the value of the address pin, and consequently, responds to that particular address according to Table 8-3.
