    8-bit I2C-bus and SMBus low power I/O port with interrupt
    [1]
    HVQFN package die supply ground is connected to both VSS pin and exposed center pad. VSS pin must be
    connected to supply ground for proper device operation. For enhanced thermal, electrical, and board level
    performance, the exposed pad needs to be soldered to the board using a corresponding thermal pad on the
    board and for proper heat conduction through the board, thermal vias need to be incorporated in the PCB in
    the thermal pad region.

    6.1 Registers
    6.1.1 Command byte
    The command byte is the rst byte to follow the address byte during a write transmission.
    It is used as a pointer to determine which of the following registers will be written or read.
    6.1.2 Register 0 - Input Port register
    This register is a read-only port. It reects the incoming logic levels of the pins, regardless
    of whether the pin is dened as an input or an output by Register 3. Writes to this register
    have no effect.
    The default ‘X’ is determined by the externally applied logic level.
