MSPM0L1305: Count external clock in the MCU

Hi Kenley,

Please refer to the page 951 of user manual.(18.2.3.2.1 Edge Count).

Thanks,

Hi Zhao,

Thank you for the reply.

My customer would like to know more details. 

Could you explain us how to do it 

This is the detailed question from customer：

For example, if you use the PA0 pin as the input pin for an external clock and want to decrease the timer count on input rise.

1. How do I set the pin? Where is the register for setting the PA0 pin as the input pin of the external clock?

2. After setting the pin, where and how can other settings (TIMx.CCCTL_xy[0/1].ACOND, TIMx.CTRCTL.CAC, etc.) be set to operate the timer to use to count the external clock?

3. Where should I enter the value if I want to count 100?

4. If the external clock is set, will all four 16-bit general-purpose timers run on the external clock, or can they be set for each timer? If possible, please let me know how to set it up.

5. Regarding pins that can be used for external clocks, is "pin with timer function" such as TIMG1_C0 can be used ?

Thank you in advance.

Best Regards,

Kenley 

Hi Kenley,

In fact, you can find an example code about edge count in the SDK.

Maybe customer can refer to it first and evaluate the function easily.

Thanks,
