Register 0 and 1: Input port 0 and 1 registers (input-only port).
It reflects the incoming logic levels of the pins, regardless of whether the pin
is defined as an input or an output. Writes to this register have no effect.
The default value ‘X’ is determined by the externally applied logic level.

Register 4 and 5: Polarity inversion port 0 and 1 registers.
This register allows the user to invert the polarity of the Input port register
data. If a bit in this register is written with ‘1’, the Input port data polarity is
inverted. If a bit in this register is written with ‘0’, the Input port data polarity
is retained.

Register 6 and 7: Configuration port 0 and 1 registers.
This register configures the directions of the I/O pins. If a bit in this register
is written with ‘1’, the corresponding pin is enabled as an input. If a bit in this
register is written with ‘0’, the corresponding pin is enabled as an output. At
reset, the device’s ports are inputs.
