The IPOL register allows the user to configure the
polarity on the corresponding GPIO port bits.
If a bit is set, the corresponding GPIO register bit will
reflect the inverted value on the pin.

INPUT POLARITY (IPOL) REGISTER
IP7:IP0: These bits control the polarity inversion of the input pins <7:0>
1 = GPIO register bit will reflect the opposite logic state of the input pin.
0 = GPIO register bit will reflect the same logic state of the input pin.
