MAX7311Detailed DescriptionThe MAX7311 general-purpose input/output (GPIO)peripheral provides up to 16 I/O ports, controlledthrough an I2C-compatible

Each transmission consists of a START condition sent bya master, followed by the MAX7311 7-bit slave addressplus R/W bit, a register address byte, 1 o

MAX7311MAX7311 generates the acknowledge bit since theMAX7311 is the recipient. When the MAX7311 is trans-mitting to the master, the master generates

Eight of the MAX7311’s nine registers are configured tooperate as four register pairs: input ports, output ports,polarity inversion ports, and configu
