    \brief

    IIC is a multi-master, multi-slave, single-ended, serial computer bus. It is typically used for attaching lower-speed peripheral
    ICs to processors and micro-controllers. Alternatively I2C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C).

    apiSWI2C using GPIOs(SDA and SCL) to emulate IIC protocol.

    <b>Features</b>
    - IIC Initialize & De-initialize function
    - IIC Send Data
    - IIC Receive Data

    <b> Operation Code Flow: </b> \n
    -# I2C Start Condition.
    -# Send data.
    -# Receive data.
    -# I2C End Condition.
