I/O 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.
Ports P10_0 to P10_7 and P11_0 to P11_7 can be used as
LED drive ports.
Segment output SEG0 to SEG55 O LCD segment output pins
Common output COM0 to COM7 O LCD common output pins
