... The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I were developed to enhance the NXP Semiconductors family of I The improvements include higher drive capability I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, and so on ...

... NXP Semiconductors 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, normally ‘1’ when no external signal externally applied because of the internal pull-up resistors ...

... NXP Semiconductors 6.3 Interrupt output The open-drain interrupt output is activated when one of the port pins change state and the pin is configured as an input. The interrupt is deactivated when the input returns to its previous state or the Input Port register is read. Note that changing an I/O from and output to an input may cause a false interrupt to occur if the state of the pin does not match the contents of the Input Port register ...
