msp430F149,说明：设置DCO时钟（台达）*（4096）使用软件FLL。DCO时钟输出P5.5作为SMCLK。DCO时钟，这是选定的SMCLK通TIMER_A的积分：LFXT1/8（4096），直到SMCLK等于德尔塔。- Descr iption: Set DCO clock to (Delta)*(4096) using software FLL. DCO clock

is output on P5.5 as SMCLK.　DCO clock, which is the selected SMCLK source for timer_A is integrated over LFXT1/8 (4096) until SMCLK is is equal to Delta.
