Value of Inversion Register :
When set to a '1', the incoming/outgoing port value is inverted.
When set to a '0', the incoming/outgoing port value is the same as in Data
Register.
Value of I/O Selection Register :
When set to a '1', respective GPIO port is programmed as an input port.
When set to a '0', respective GPIO port is programmed as an output port.
Value of Output Data / Input Data :
If a port is assigned to be an output port, then its respective bit can be
read/written.
If a port is assigned to be an input port, then its respective bit can be read only.
Note :
DIO_IN0/DIO_IN1/DIO_IN2/DIO_IN3 are programmed as
** Attention : If
DIO_IN0/DIO_IN1/DIO_IN2/DIO_IN3
can only offer a normal signal transfer.(NOT amplified signals.)
DIO_OUT0/DIO_OUT1/DIO_OUT2/DIO_OUT3 are fixed as
