Normal mode is LPM0.// USCI_A0 RX interrupt triggers TX Echo.// If UCOS16=1, UCBRx=Fbrclk/(16*Baudrate)// Baud rate divider with UCBRx = 1MHz/(16*9600) = ~6.8// ACLK = REFO = ~32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz// See User Guide for baud rate divider table//// MSP430F552x// -----------------// /|\| |// | | |// --|RST |// | |// | P3.3/UCA0TXD|------------>// | | 9600 - 8N1// | P3.4/UCA0RXD|
