Description
Reserved
The values read from these Bits are always 0. Do not set these Bits.
Frame Number CRC OK Bit
Set by hardware after a non corrupted Frame Number in Start of Frame Packet is
received.
Updated after every Start Of Frame packet reception.
Note: The Start Of Frame interrupt is generated just after the PID receipt.
Frame Number CRC Error Bit
Set by hardware after a corrupted Frame Number in Start of Frame Packet is
received.
Updated after every Start Of Frame packet reception.
Note: The Start Of Frame interrupt is generated just after the PID receipt.
Reserved
The values read from this Bits are always 0. Do not set this bit.
Frame Number
Upper 3 Bits of the 11-bit Frame Number. It is provided in the last received SOF
packet. FNUM does not change if a corrupted SOF is received.
Frame Number
