IP0 to IP4 - Input Port registers
These registers are read-only. They reflect the incoming logic levels of the port pins
regardless of whether the pin is defined as an input or an output by the I/O Configuration
register. If the corresponding Px[y] bit in the PI registers is set to logic 0, or the inverted
incoming logic levels if the corresponding Px[y] bit in the PI register is set to logic 1. Writes
to these registers have no effect.
The Polarity Inversion register can invert the logic states of the port pins. The polarity of
the corresponding bit is inverted when Px[y] bit in the PI register is set to logic 1. The
polarity of the corresponding bit is not inverted when Px[y] bits in the PI register is set to
logic 0.
