MSPM0G1506:About Errata VREF_ERR_03

Thank you,

I am configuring VREF in sysconfig; is it possible to apply a workaround for this erratum?

Yes, init the Vref manually.

Output high to Vref+ pin by GPIO.

Then reset IOMUX and init Vref module.

OK,

I understand that the SYSCFG_DL_VREF_init(void) function automatically generated by SYSCONFIG should not be used. Is that correct?

You need to charge Vref+ using GPIO, then reset IOMUX and call

SYSCFG_DL_VREF_init

to enable vref+ module.

Since Vref is analog function, IOMUX need to keep in reset status.

A response has not been received.
Is it correct to understand that enabling the VREF+ module after using the GPIO cannot be achieved through SYSCONFIG?

I will implement the countermeasure in my program, but how many seconds should the precharge via GPIO be performed?

Yes~ syscfg only support simple peripherals init code generation.
