Product data sheet
7.1 Device address
Refer to
Following a START condition, the bus master must send the target slave address followed
by a read or write operation. The slave address of the PCA9629 is shown in
Slave address pins AD1 and AD0 choose one of 16 slave addresses. To conserve power,
no internal pull-up resistors are incorporated on AD1 and AD0.
addresses by connecting the AD0 and AD1 to V
The last bit of the first byte defines the reading from or writing to the PCA9629. When set
to logic 1 a read is selected, while logic 0 selects a write operation.
