MSPM0G3519: MSPM0G3218: Timer basic specifications

Part Number: MSPM0G3519
Other Parts Discussed in Thread: MSPM0G3218

Dear TI Expert,

From datasheet, I see that the MSPM0G3218 supports two basic timers:

But I can not found the information for these timers in MSPM0 G-Series 80MHz Microcontrollers
Technical Reference Manual.

I have a look in the SDK, it seems like we have a little difference with TIMx Registers

Please help me clarify that or give me the information for timerB.

Thank you.

    Hi Hoc,

    The TRMs are expected to be updated next week with the Basic Timer section.

    If you do not see an updated release within the next 2 weeks, please re-open this thread or start a new one to bring attention to this matter.

    Best,

    Owen

    Hi Owen,

    Are these software timers? Do they ultimately run based on a hardware timer?

    Can we use them for OS scheduling?
    From my point of view, OS scheduling should rely directly on a hardware timer (such as TimerG or TimerA).

    Also, do these basic timers support any PWM output channels?

    BRs,
    Hoc

    Hi Hoc,

    The Basic Timer module is not a software timer. It is a configurable array of 2-8 simple counters.

    I'm not 100% sure if you can use a TIMB for OS scheduling, but I don't think so. Usually this is with systick.

    There will be an example in the TIMB section of the TRM that outlines how to generate a PWM signal using GPIO and two TIMB counters.

    Best,

    Owen
