MSPM0G1107: QEI mode and CAPTURE mode

Part Number: MSPM0G1107

Tool/software:

Dear expert,

My customer has some questions about MSPMOG1107, please help on these questions, thank you.

  1. Current requirement : mspm0g1107 uses timer to capture the high/low level duration of gpio (A10). What are the recommended ways and demos for current requirements?
  2. At present, using CAPTURE mode, it is found that only rising edge or falling edge trigger timer interrupt can be selected, and there is no two-sided edge trigger mode selection. Is it our mode selection exception or version exception? How to solve it?
  3. We set the register CCOND to 0x03, but after entering the interrupt, we are not clear about the interrupt mode and how to obtain the high/low level duration. How can we solve this problem?
  4. When selecting QEI mode, it is found that a single GPIO cannot be selected separately, such as and resolved, and how to determine the interrupt mode and the duration of obtaining the high/low level of GPIO?

    Can you tell me what the signal like? What is the application.

    Can you ask your customer refer to this example. For only rising edge or falling edge, it is for duty capture. For two-side edge, it is for period capture.
