snvs_hp_VIO_5 is muxed on pin E5 and snvs_hp_VIO_5_CTL is muxed on pin F5. I can not find any details on the function of these (2) pins.
Hi Rene
these are tamper pins, description can be found in
Security Reference Manual for the i.MX 6ULL Applications Processor

Igor,
We are using the i.MX 6UltraLite – MCIMX6G3CVM05AB.
I looked in the Security Reference Manual for the i.mX 6UltraLite Applications Processor – Rev 0, 04/2016 and I could not find any reference to these pins.
What page or section of the SRM are these pins discussed?
Regards,
Rene

Hi Rene
references can be found in Table 7-4. SNVS _HP security violation sources,
Security violation input 5, sect.7.9.5 SNVS_HP Security Interrupt Control (HPSICR),
sect.7.9.8 SNVS_HP Security Violation Status (HPSVSR), Security Violation Interrupt 5 Enable
Tamper usage is similar to AN12210 Tampering Application for i.MX7Dsabresd
https://www.nxp.com/docs/en/application-note/AN12210.pdf

Igor,
Thanks.
Table 7-7 SNVS_LP security violation sources list external tamper pin and external tamper pin 2.
I thought there were (10) external tamper pins which could be configured for active(paired) or passive.
Also, the Wire-Mesh Tamper, does that refer to an on-chip wire mesh?
Are there multiple on-chip wire meshes? There are references to (2) meshes.

Rene
