CMOS I/O ports. Each port has an I/O select direction
register, allowing each pin in the port to be directed for input
or output individually.
Any port set to input can be set to use a pull-up resistor or not
by a program.
P1_0 to P1_7 also function as LED drive ports.
Input-only ports
These pins are provided for XIN clock generation circuit I/O.
