    \brief
    GPIO (Generic Purpose Input/Output) is a generic pin on an integrated circuit, which can be programmed to be used to either 
    accept input or provide output to external devices depending on user desires and application requirements

    <b> Features </b>
    - GPIO pin direction can be set by software
    - User/Device can read value of GPIO register
    - Support interrupt enable/disable mode
    - Support diffrent power state of certain GPIO pin
