Hi community,


Our customer have a simple question.


Would you let me know the condition when i.MX6DQ judges as POR_B is released?
When POR_B input voltage reaches to VIH (VDD_SNVS_IN * 0.7)?
Or when it exceeds VIL (VDD_SNVS_IN * 0.3)?



Actually, POR_B slew rate on their custom board is very low (slope is gentle) to expand POR_B assertion time for ERR007926 workaround.
However, if i.MX6Q judges as POR_B is released when POR_B voltage exceeds VIL, their workaround is not enough.

In fact, they have to start mass production soon, so they want to clear it ASAP.
I would appreciate it if you could give us reply rapidly.


Best Regards,
