Message FIFOs 31 FIFOs, configurable as transmit or receive
FIFOs One Transmit Queue (TXQ) Transmit Event FIFO (TEF) with 32 bit time stamp
Message Transmission Message transmission prioritization:
-Based on priority bit field, and/or
-Message with lowest ID gets transmitted first
using the Transmit Queue (TXQ) Programmable automatic retransmission
attempts: unlimited, 3 attempts or disabled Oscillator Options 40, 20 or 4 MHz crystal, or ceramic resonator; or
external clock input Clock output with prescaler
SPI Interface Up to 20 MHz SPI clock speed Supports SPI modes 0,0 and 1,1 Registers and bit fields are arranged in a way to
enable efficient access via SPI
Safety Critical Systems SPI commands with CRC to detect noise on SPI
interface Error Correction Code (ECC) protected RAM
