MSP430F6746: I have a question about UCS on MSP430.

I have a question about UCS on MSP430.

After setting UCSCTL4, when setting UCSCTL5, is there any problem without adding a wait?

Da

  • Hi, Da, 

    There is no problem to set UCSCTL5 after setting UCSCTL4 without adding wait. Since UCSCTL5 is to config the divider and UCSCTL4 is to select the clock source, it is better to config UCSCTL5 firstly before setting UCSCTL4 so that the correct frequency can be effective immediately. 

    In addition, before setting UCSCTL4 to select clock source, it is better to wait for the target clock source is available. Please refer to the datasheet clock specification for the start-up time of different clock sources. 

    Best regards,

  • thank you for your answer.

    Best Regards,
    Da
