MSP430FR6972: ACLK 频率问题

板子上焊接了32.768khz的晶振，程序是用 CS_initClockSignal(CS_ACLK, CS_LFXTCLK_SELECT, CS_CLOCK_DIVIDER_1)修改时钟源，在debug仿真的时候CS_getACLK(); 获取的aclk的频率不是32768而是39062，这是怎么回事。

If a oscillator fault is set, the frequency returned will be based on the fail safe mechanism of CS module. The user of this API must ensure that CS_externalClockSourceInit API was invoked before in case LFXT or HFXT is being used.

您是否使用了CS_externalClockSourceInit API ？
