An IRQ is received on message RX/TX (or RX errors), with
separate IRQs for RX and TX.

0-byte CAN FD frame as the worst case:
- 17 slow bits = SOF + 11 ID + R1 + IDE + EDL + R0 + BRS
- 23 fast bits = ESI + 4 DLC + 0 DATA + 17 CRC + CRC delimeter
- 12 slow bits = ACK + DEL + 7 EOF + 3 IFS
- all currently supported cars are 0.5 Mbps / 2 Mbps

1 / ((29 bits / 0.5Mbps) + (23 bits / 2Mbps)) = 14388Hz
