7.4.3 PI0 to PI4 - Polarity Inversion registers

These registers allow inversion of the polarity of the corresponding Input Port register.

Px[y] = 0: The corresponding Input Port register data polarity is retained.

Px[y] = 1: The corresponding Input Port register data polarity is inverted.

Where ‘x’ refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).

 

7.4.4 IOC0 to IOC4 - I/O Configuration registers

These registers configure the direction of the I/O pins. 

Cx[y] = 0: The corresponding port pin is an output.

Cx[y] = 1: The corresponding port pin is an input.

Where ‘x’ refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
