9.5.1.1 I2C Address Selection

The TLA202x have one address pin (ADDR) that configures the I2C address of the device. The ADDR pin can connect to GND, VDD, or SCL (as shown in Table 2), which allows three different addresses to be selected with one pin. At the start of every transaction, that is between the START condition (first falling edge of SDA) and the first falling SCL edge of the address byte, the TLA202x decode its address configuration again.

Table 2. ADDR Pin Connection and Corresponding Slave Address

ADDR PIN CONNECTION SLAVE ADDRESS
GND 1001 000
VDD 1001 001
SCL 1001 011
