This is an example of an HW configuration. All pins can be used
as GPIOs.

The PCA9552 has 3 GPIOs, add them.
See 'PCA9552 Product Datasheet Rev. 05 - 9 March 2006',
chapter 6.4 'Pins used as GPIOs':
LED pins not used to control LEDs can be used as general
purpose I/Os (GPIOs).
For use as input, set LEDn to high-impedance (01) and then
read the pin state via
