BAUD_RATE

#define BAUD_RATE   9600

This example shows how to configure the UART module to transmit data in idle line multiprocessor mode.

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.
