7.15.3.1 Features
7.15.3 USB OTG controller
7.16.1 Features
7.16 SD/MMC card interface
7.17 Fast general purpose parallel I/O
USB OTG is a supplement to the USB 2.0 Specification that augments the capability of
existing mobile devices and USB peripherals by adding host functionality for connection to
USB peripherals.
The OTG Controller integrates the host controller, device controller, and a master-only I
interface to implement OTG dual-role device functionality. The dedicated I
controls an external OTG transceiver.
Remark: The SD/MMC card interface is available on parts LPC1788/87/86/85 and parts
LPC1778/77/76.
The Secure Digital and Multimedia Card Interface (MCI) allows access to external SD
memory cards. The SD card interface conforms to the SD Multimedia Card Specification
Version 2.11.
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.

Supports per-port power switching
Fully compliant with On-The-Go supplement to the USB 2.0 Specification, Revision
1.0a.
Hardware support for Host Negotiation Protocol (HNP).
Includes a programmable timer required for HNP and Session Request Protocol
(SRP).
Supports any OTG transceiver compliant with the OTG Transceiver Specification
(CEA-2011), Rev. 1.0.
The MCI provides all functions specific to the SD/MMC memory card. These include
the clock generation unit, power management control, and command and data
transfer.
Conforms to Multimedia Card Specification v2.11.
Conforms to Secure Digital Memory Card Physical Layer Specification, v0.96.
Can be used as a multimedia card bus or a secure digital memory card bus host. The
SD/MMC can be connected to several multimedia cards or a single secure digital
memory card.
DMA supported through the GPDMA controller.
