/*******************************************************************************
* Function Name: UART_Enable
****************************************************************************//**
*
* Enables UART component operation: activates the hardware and
* internal interrupt. It also restores TX interrupt sources disabled after the
* UART_Stop() function was called (note that level-triggered TX
* interrupt sources remain disabled to not cause code lock-up).
* For I2C and EZI2C modes the interrupt is internal and mandatory for
* operation. For SPI and UART modes the interrupt can be configured as none,
* internal or external.
* The UART configuration should be not changed when the component
* is enabled. Any configuration changes should be made after disabling the
* component.
* When configuration is set to “Unconfigured UART”, the component
* must first be initialized to operate in one of the following configurations:
* I2C, SPI, UART or EZ I2C, using the mode-specific initialization API.
* Otherwise this function does not enable the component.
