GPIO [15:0] allow five multiplex modes.
GPIO [103:16] and GPIO_A [3:0] have four multiplex modes.
Using a pin as GPIO means always to give up other functionalities. Some
functions are duplicated to enhance the chance to use them without giving up
other vital functions.
Using original and (dup) functions in parallel is not recommended.
Default function of GPIOs after CPU power up is function 03, except GPIO12
(function 02-reset_done) and GPIO [31:16] (function 00 - DATA[15:0]).
the default function is written bold,
# means low active signal,
(dup) means function is available multiple times.
