Tool/software:

Hi everyone,

I downloaded the recent User Manual of the MSPM0l1303 uC, revision D (SLAU847D).

In the OPA section it says:

but in the Registers section I can't find the CFGBASE register nor the GBW bit.

Is this information somewhere else?

Thank you everybody,

Fabio

Hi Fabio

Yes, this functionality is present in production silicon. You can find CFGBASE and the functionality on the register of CCS

There may be something wrong with TRM. I will follow up to request the update on TRM

Thanks!

ok, thank you Xiaodong.

I found the associated function in the SDK (DL_OPA_setGainBandwidth) but I have some troubles in using it. I couldn't set the bit.

A part form waiting the STAT.RDY == 1, do you know if there is any known issue on those registers?

what I meant was:

I can not write that register, it does not changes its value but I am not sure why.

thank you,

Fabio

Hi Fabio

I run the "opa_burnout_current_source_to_adc" example code of LP_MSPM0L1306 on SDK

GBW.CFGBASE can be set to 1 by this example code.

I tested this code on CCS environment.

Could you please test this example code as well?

Thanks

Hi Fabio,

Please try to set GBW register before enable OPA.

Thanks,

Hi everyone,

thank you xiaodong Li,

it works.

I think this indication on the SDK 2.0.1.0 is a bit misleading:

as I wrote to Xiaodong,
