//  MSP-FET430P440 Demo - USART0, 9600 UART Echo ISR, DCO SMCLK
//
//  Description: Echo a received character, RX ISR used. Normal mode is LPM0.
//  USART0 RX interrupt triggers TX Echo.
//  Baud rate divider with 1048576hz = 1048576Hz/9600 = ~109.23 (06Dh|03h)
//  ACLK = LFXT1 = 32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz
//  //* An external watch crystal between XIN & XOUT is required for ACLK *//
