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.
