|
The SOCIONEXT Milbeaut SDHCI controller is a specialized SD Host
|
|
Controller found in some of Socionext's Milbeaut image processing SoCs.
|
|
It features a dedicated "bridge controller." This bridge controller
|
|
implements special functions like reset control, clock management for
|
|
various SDR modes (SDR12, SDR25, SDR50) and physical pin property settings.
