7.12.2.1 Features
7.12.3.1 Features
7.12.2 USB host controller (LPC1769/68/66/65 only)
7.12.3 USB OTG controller (LPC1769/68/66/65 only)
7.13 CAN controller and acceptance filters (LPC1769/68/66/65/64 only)
The host controller enables full- and low-speed data exchange with USB devices attached
to the bus. It consists of a register interface, a serial interface engine, and a DMA
controller. The register interface complies with the OHCI specification.
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 controls an external OTG transceiver.
The Controller Area Network (CAN) is a serial communications protocol which efficiently
supports distributed real-time control with a very high level of security. Its domain of
application ranges from high-speed networks to low cost multiplex wiring.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router among a number of CAN buses in
industrial or automotive applications.
