/*******************************************************************************
* Function Name: I2C_1_Stop
********************************************************************************
*
* Summary:
*  Disables the SCB component and its interrupt.
*  It also disables all TX interrupt sources so as not to cause an unexpected
*  interrupt trigger because after the component is enabled, the TX FIFO 
*  is empty.
*
* Parameters:
*  None
*
* Return:
*  None
*

    * For SCB IP v0, it is critical as it does not mask-out interrupt
    * sources when they are disabled. This can cause a code lock-up in the
    * interrupt handler because TX FIFO cannot be loaded after the block
    * is disabled.
