TPM low power

GustavoSanchez — Sat, 03 Dec 2022 00:08:22 GMT

Hi, is it possible to configure the Timer/PWM Module in low power mode (lls)?

If it is, what register is neccessary to configure?

I am actually using MCGIRCLK clock in the SetTPMClock and kCLOCK_McgInternalRefClk macro in the SetTimerPeriod function.

Thanks.

Hi @GustavoSanchez,

Could you be so kind to specify the part number, SDK and IDE version you are currently using for your project?

Thanks,

Edwin.

Hi @GustavoSanchez

The LLS mode is not compatible with the TPM module, it is functional in STOP/VLPS mode.

Let us know if you have another question.

Best Regards, MIguel.

Hi, Miguel thanks for your answer.

And yes I have another question.

Is there another way to use a timer in lls mode? Im not sure if the PIT module have this capability.

thanks.

Hi @GustavoSanchez

On chapter 7.5 Module operation in Low-Power modes on your KL17 reference manual, you will find a table that says the functionality of your board modules in different power-modes. Based on the tables LLS section, the PIT module stay static (Module Registers states and associated memories are retained).

Let me know if you have another question.

Best Regards, Miguel.
