EUSCI_A0 External Loopback test using EUSCI_A_UART_init API

Description: This demo connects TX to RX of the MSP430 UART The example code shows proper initialization of registers and interrupts to receive and transmit data.

ACLK = BRCLK = 32.768kHz, MCLK = SMCLK = DCO/8 = ~1MHz

       Tested on MSP430F67791A

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• UART peripheral
• GPIO Port peripheral (for UART pins)
• UCA0TXD
• UCA0RXD

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• USCI_A0_VECTOR.
