The STR91xFA EMI bus is a very flexible bus and is user programmable. The bus can be configured to interface to different types of memory devices, including SRAM, flash memory, ROM or PSRAM.

This application note covers the EMI asynchronous mode configuration for interfacing to standard memory devices.
