PMODE and RESET PIN
We have following hardware configuration:
PMODE: 0F1 (SPI => USB) powered from 1.8V because its in the VIO1 domain.
We are not sure about how to power the RESET PIN cuircut.
If we power it with 3.3 V (because its in the CVDDQ domain), SPI boot will NOT work.
If we power it with 1.8 V (in fact wrong, because CVDDQ domain is 3.3V), SPI boot will work.
What is the right power configuration ?
