 CircuitPython module for the PCA9555 and compatible expanders.
 The PCA9555 is a basic 16 pin I2C expander.
-    *Configurable pins as input or output
-    *Per pin polarity inversion. This inverts the value that is returned when an input port
-     is read. Does not affect the pins set as outputs.
-    *Pin change interrupts. An interrupt is generated on any pin change for a pin configured
-     as an input. The interrupt signal is cleared by a change back to the original value of
-     the input pin or a read to the GPIO register.This will have to be detected and tracked in
-     user code. There is no way to tell from the device what pin caused the interrupt.
