hi team,

 

I would like to ask about the handling of the following unused pins.

- TAMPER_A/B

- MECH_C/D

- XP/XN

- YP/YN

My customer thinks those pins should be pulled  to high when unused for security.

If so, could you show me what register value should be used for pull-up?

 

Thanks,

Miyamoto
