I want to use hyperflash

[aoz.1]

I want to use hyperflash (S26KS512 or S26KL512) with stm32h723zet6 microcontroller.

The memory has "Phase Shifted Clock" pins.

What should I do with them? Connect to GND or VCC or Not Connected?

Hyperbus interface (stm32) support 1.8v?

Should I use a 1.8 volt power supply (VDD 1.8V)?

Can I use 3.3 volt(VDD 3.3V) power supply with 1.8v hyperbus?

Seems like entirely the wrong subforum to post this.

The KL model looks to be the 2.7 - 3.6V part, I certainly wouldn't be using the 1.8V part at voltages exceeding the maximums specified.
