7.4.3 PI0 to PI4 - Polarity Inversion registers
7.4.4 IOC0 to IOC4 - I/O Configuration registers
These registers allow inversion of the polarity of the corresponding Input Port register.
Where ‘x’ refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
These registers configure the direction of the I/O pins.
Where ‘x’ refers to the bank number (0 to 4); ‘y’ refers to the bit number (0 to 7).
Px[y] = 0: The corresponding Input Port register data polarity is retained.
Px[y] = 1: The corresponding Input Port register data polarity is inverted.
Cx[y] = 0: The corresponding port pin is an output.
Cx[y] = 1: The corresponding port pin is an input.
