Hi experts,

The CMPSS2 HP3 input has two input pin. How to check which pin is active?

For example, in syscfg, which pin is CMPSS2 HP3 input pin

Thanks,

Hello Leo,

Which package are you using? B0 on CMPSS2 HP3 is only available on 100PZ pin package per datasheet.

Hi Leo,

Did you check muxing for 100pz in datasheet and TRM?

Leo,

I confirmed that there is an error in the above table. B0/C11 should be on CMP2 HPMXSEL = 4 and LPMXSEL = 4.

A10/B1/C10 are correct as shown.

Will file a bug to get the documentation corrected.

Hi Matthew,

Thank you for you confirm.

However, the setting in the syscfg is the same with the error DS.

Thanks,

Leo

Leo,

Yes, we will need to get that corrected as well. Customer has option of manually correcting the board.c/board.h files that get generated by sysconfig tool for now.

If they are using A10/B1/C10, these are correct and no action is needed, it is only if they use sysconfig for B0/C11

Best,

Matthew
