LPC3130_3131_1
Preliminary data sheet
6.10 High-speed Universal Serial Bus 2.0 On-The-Go (OTG)
6.11 DMA controller
The USB OTG module allows the LPC3130/3131 to connect directly to a USB host such
as a PC (in device mode) or to a USB device in host mode. In addition, the LPC3130/3131
has a special, built-in mode in which it enumerates as a Device Firmware Upgrade (DFU)
class, which allows for a (factory) download of the device firmware through USB.
This module has the following features:
The DMA Controller can perform DMA transfers on the AHB bus without using the CPU.
