MSPM0C1103: Using of Watchdog in MSPM0C1103

Part Number: MSPM0C1103

Tool/software:

Good morning TI team

I am using MSPM0C1103 micro-controller with the following setup: IAR Embedded Workbench IDE and J-link (by SEGGEER).

In MSPM0C1103 there is a Cortex M0+:

  1. I need to know if it’s possible to use the watchdog internal to M0, where it’s always enabled (default) at power-up (see M0 ARM spec). If M0 watchdog is implemented in MSPM0C1103, how can I use it?
  2. My software uses the WWDT timer and it is configured and enabled only by application software. Is it possible to enable it at power-up? In old microcontrollers (@8bit), this feature was possible to do by a particular option bit and not by application software. This ensures that the WD always starts at startup. I would like to have WWDT enabled (default) at power-up and not by application software.

 Thank you for your support.

    Hi Michele,
    1. The MSPM0 requires this internal watchdog module to be configured before it starts running i.e. it is not always enabled nor it is enabled at power-up. 

    2. It is not possible to enable at power-up. The MSPM0 devices don't have this similar feature that MSP430 devices had. 

    Best Regards,
