supply voltage

[1] HVQFN package die supply ground is connected to both V_SSpin and exposed center pad. V_SSpin 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.

read/write byte

The command byte is the first 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 reflects the incoming logic levels of the pins, regardless

of whether the pin is defined 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.
