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.

SMCLK = MCLK = BRCLK = DCOCLKDIV = ~1MHz, ACLK = 32.768kHz

      MSP430FR2xx_4xx Board

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.
