6.18 SD/MMC card interface
6.19 LCD interface
The Secure Digital and Multimedia Card Interface (MCI) is an interface between the APB
and multimedia and/or secure digital memory cards.
The interface provides all functions specific to the Secure Digital/MultiMedia memory
card, such as the clock generation unit, power management control, command, data
transfer, interrupt generation, and DMA request generation.
The LCD interface contains logic to interface to a 6800 or 8080 bus compatible LCD
controller. The LCD interface is compatible with the 6800 bus standard and the 8080 bus
standard, with one address pin (RS) for selecting the data or instruction register.
The LCD interface makes use of a configurable clock (programmed in the CGU) to adjust
the speed of the 6800/8080 bus to the speed of the connected peripheral.

Fully compliant with USB 2.0 specification (high-speed and full-speed).
8 logical endpoints = 16 physical endpoints.
Supports Control, Bulk, Interrupt and Isochronous endpoints.
Endpoint type selection by software
Endpoint maximum packet size setting by software
Supports Soft Connect feature (requires an external 1.5 k resistor between the
CONNECT pad and 3.3 V).
Supports bus-powered capability with low suspend current.
Two DMA channels, assignable to any of 4 physical endpoints.
Supports Burst data transfers on the AHB.
Supports Retry and Split transactions on the AHB.
Conformance to Multimedia Card Specification v2.11 .
Conformance to Secure Digital Memory Card Physical Layer Specification, v0.96 .
Use as a multimedia card bus or a secure digital memory card bus host. It can be
connected to several multimedia cards, or a single secure digital memory card.
DMA transfers are supported through the Simple DMA facility.
8-bit or 4-bit parallel interface mode: 6800-series, 8080-series.
Selectable bus frequency supports high and low speed LCD controllers.
Supports polling the busy flag from the LCD controller to avoid CPU polling.
Contains a 16 B FIFO for sending control and data information to the LCD controller.
Contains a serial interface which uses the same FIFO for serial transmissions.
Supports FIFO level flow control to the General Purpose DMA controller.
