MSPM0G3519: Vref external capacitor refresh time

Need some time for internal check.

If user don't use COMP in below mode, they can ignore this spec:

Vref - > DAC8 -> COMP in standby mode.

Hi Helic,

Thank you. Could you please give full details of what the "Vref external capacitor refresh time" corresponds to? I looked at the VREF and COMP chapters in the TRM and device datasheet, and could not relate "Vref external capacitor refresh time" to anything in the TRM or datasheet...

Best regards,
François.

Hi, Now, I can confirm this one, need double check with customer.

For detailed description, it's still under checking now.

But have plan to add some info in TRM or other options.

We also have config in Vref in syscfg:

The datasheet spec limits above config in red box.

Thank you, Helic. I see in SysConfig that the VREF minimum sampling time must be 31 us or above. On the other hand, the datasheet says that the Vref external capacitor refresh time should be at least 31us.

Is it correct to conclude that these 2 values correspond to the same parameter? If so, it may be good to rename the parameter in the datasheet so it is the same as in the TRM.

Best regards,
François.
