7.6.2 Register 1 - Input port 1 register
This register is read-only. It reects the incoming logic levels of the pins, regardless of
whether the pin is dened as an input or an output by the Conguration register. Writes to
this register will be acknowledged but will have no effect.
The default ‘X’ is determined by the externally applied logic level.
7.6.3 Register 2 - Polarity inversion port 0 register
This register allows the user to invert the polarity of the Input port register data. If a bit in
this register is set (written with ‘1’), the corresponding Input port data is inverted. If a bit in
this register is cleared (written with a ‘0’), the Input port data polarity is retained.
