Digital input port configuration
The Digital Input Port offers flexible mapping of the input busses for PORTA and PORTB and
allows individual Bus Flipping (MSB to LSB) for each group of 8- or 10-bit inputs. The purpose
of this flexible mapping is to ease the circuit board design when interfacing to other devices.
