Register Name:
Access Type:
Reset Value:
• FNUM: Frame Number
Set by hardware. These bits are the 11-bit frame number information. They are provided in the last received SOF packet.
Cleared by hardware upon receiving a USB reset.
Note that FNUM is updated even if a corrupted SOF is received.
• FNCERR: Frame Number CRC Error
Set by hardware when a corrupted frame number is received. This bit and the SOF interrupt flag are updated at the same
time.
Cleared by hardware upon receiving a USB reset.
