/*******************************************************************************
* Function Name: I2CM_Start
********************************************************************************
*
* Summary:
* Invokes SCB_Init() and SCB_Enable().
* After this function call, the component is enabled and ready for operation.
* When configuration is set to "Unconfigured SCB", the component must first be
* initialized to operate in one of the following configurations: I2C, SPI, UART
* or EZ I2C. Otherwise this function does not enable the component.
*
* Parameters:
* None
*
* Return:
* None
*
* Global variables:
* I2CM_initVar - used to check initial configuration, modified
* on first function call.
