5.10.7 Controller Area Network - Flexible Data-rate (CAN-FD)
The CAN-FD module supports both classic CAN and CAN FD (CAN with Flexible Data-Rate)
specifications. CAN FD feature allows high throughput and increased payload per data frame. The classic
CAN and CAN FD devices can coexist on the same network without any conflict.
The CAN-FD has the following features:
• Conforms with CAN Protocol 2.0 A, B and ISO 11898-1
• Full CAN FD support (up to 64 data bytes per frame)
• AUTOSAR and SAE J1939 support
• Up to 32 dedicated Transmit Buffers
• Configurable Transmit FIFO, up to 32 elements
• Configurable Transmit Queue, up to 32 elements
• Configurable Transmit Event FIFO, up to 32 elements
• Up to 64 dedicated Receive Buffers
• Two configurable Receive FIFOs, up to 64 elements each
• Up to 128 11-bit filter elements
• Internal Loopback mode for self-test
• Mask-able interrupts, two interrupt lines
• Two clock domains (CAN clock / Host clock)
• Parity / ECC support - Message RAM single error correction and double error detection (SECDED)
mechanism
• Full Message Memory capacity (4352 words).

5.10.8 Serial Communication Interface (SCI)
The SCI has the following features:
• Standard universal asynchronous receiver-transmitter (UART) communication
• Standard non-return to zero (NRZ) format
• Double-buffered receive and transmit functions
• Asynchronous or iso-synchronous communication modes with no CLK pin
• Capability to use Direct Memory Access (DMA) for transmit and receive data
• Two external pins: RS232_RX and RS232_TX
