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 between two of CAN buses in industrial
or automotive applications.
Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN
Library block, but the 8-bit registers of those devices have been combined in 32-bit words
to allow simultaneous access in the ARM environment. The main operational difference is
that the recognition of received Identifiers, known in CAN terminology as Acceptance
Filtering, has been removed from the CAN controllers and centralized in a global
Acceptance Filter.
