10.3.8 GPIO Multi-Function Pin Selection Register (Index=25h, Default=00h)
If the enabled bits are not set, the multi-function pins will perform the original functions. On the other
hand, if they are set, they will perform the GPIO functions. This register can be read from any LDN, but
can only be written if LDN=07h.
