It works materially the same.

You set commands as being 8-bit, and then select the width of command, address and data transactions at a clock level to 1, 2 or 4-bits.

Hello @Aries16;

 

The OCTOSPI interface supports QuadSPI memories. Please look at FAQ: Does OctoSPI interface support QuadSPI memories?.

You can find in Getting started with Octo-SPI, Hexadeca-SPI, and XSPI interfaces on STM32 MCUs - Application note and precisely section "7.2 OCTOSPI configuration with STM32CubeMX" an example of Quad-SPI PSRAM memory connected to OCTOSPI interface.
