Description: This program demonstrates a half-duplex 9600-baud UART using // Timer_A3 using no xtal and an external resistor for DCO ROSC. DCO used for // TACLK UART baud generation. The program will wait in LPM4, echoing back // a received character using 8N1 protocol. On valid RX character, the // character is echoed back. // Using a 100k resistor on ROSC, with default DCO setting, set DCOCLK ~ 2MHz. // ACLK = n/a, MCLK = SMCLK ~2MHz DCOCLK
