This is an USB 3.1 Gen1 dual-role controller, which is compliant to USB 2.0/USB 3.1 Gen1 specifications. The controller can act as a standard
host or peripheral for easy system implementation. The role can be selected via static pin selection.
This is a universal serial bus (USB) 2.0 On-The-Go (OTG) Controller, which can play dual-role, as a host or a device controller. When it acts as a host, it contains a USB host controller to support all speed transactions.
Designed to work with a wide variety of SPI bus variants, the core supports run-time control of several SPI protocol parameters. For example, the SPI frame width can be 1 to 4 bytes, the
most significant bit position in a frame, serial clock phase and polarity are all software- programmable. In master mode the core can control up to 32 slaves. A software controllable clock generator derives the serial clock for master mode, by dividing the frequency of a clock line dedicated for that purpose
The CAN protocol uses a multi-master bus configuration for the transfer of frames be- tween nodes of the network and manages error handling with no burden on the host processor. The core enables the user to set up economic and reliable links between vari- ous components. It appears as a memory-mapped I/O device to the host processor, which accesses the CAN core to control the transmission or reception of frames.
The CAN core is easy to use and integrate, featuring programmable interrupts, data and baud rates; a configurable number of independently programmable acceptance filters; and a generic processor interface or optionally an AMBA APB, or AHB-Lite interface. It imple- ments a flexible buffering scheme, allowing fine-tuning of the core size to satisfy the requirements of each specific application
