Part Number: MSPM0C1104

Tool/software:

Hi team,

Customer is evaluating M0C1104 16 pin package. They have some questions. Please help clarify. Thank you.

  1. Could the two pins of SWDIO, SWCLK be used for GPIO or ADC usage ? Would this affect flash programming ?
  2. Could M0C1104 use SPI to update ？

    Yes, the SWDIO and SWCLK can be reused for GPIO, and PA20 can be used for ADC usage.

    However, the swd will be disabled in application code if it is reused for other function. So, it is recommend adding some delay before SWD disable code. In that way, you can re-flash code at that time.

    You can use secondary BSL to realize SPI update.
