15. SD/MMC Controller
The hard processor system (HPS) provides a Secure Digital/Multimedia Card (SD/MMC) controller for interfacing to external SD and MMC flash cards, secure digital I/O (SDIO) devices, and Consumer Electronics Advanced Transport Architecture (CE-ATA) hard drives. The SD/MMC controller enables you to store boot images and boot the processor system from the removable flash card. You can also use the flash card to expand the on-board storage capacity for larger applications or user data. Other applications include interfacing to embedded SD (eSD) and embedded MMC (eMMC) non-removable flash devices.
The SD/MMC controller is based on the Synopsys® DesignWare® Mobile Storage Host (SD/MMC controller) controller.
This document refers to SD/SDIO commands, which are documented in detail in the Physical Layer Simplified Specification, Version 3.01 and the SDIO Simplified Specification, Version 2.00 described on the SD Association website.
