Hello,
I'm using the STM32N657 processor and have the HEXASPI device running at 1.8V.
VDDIO2 is connected to 1V8 supply (which affects: PO[5..0] and PP[15..0]
The FMC is placing the A23 line on pin PO1 (this is the only option for the FMC-A23) and the FMC device is running at 3.3V. Can I place a pullup to 3.3V on PO1, or will this affect/blow the GPIO connected to 1.8V -OR- do I need to place a voltage translator on that pin?
