GPIO P0~P15
、
8051A P0~P9
：
Above is Port I/O, each port has 8 pins, if you need 8 bits of GPIO, just
simply choose those Port I/O. The 8051A functions are not opened for users
because the internal 8051A already simulated 8051A as Keyboard Controller
in BIOS.
Port0~Port5 Bit Mux
：
Port 0 to Port5 are Bit Mux, which means every single bit can be selectable
from Rich-I/O G0 or Rich-I/O G1.
Port6~Port15 Port Mux
：
Port 6 to Port 15 are Port Mux, which means the whole port can only be
selected to one function. For example, select the whole port for GPIO, but
not 4 pins for GPIO and other 4 pins for other function.
