Frame Number CRC OK
This bit is set by hardware when a new Frame Number in Start of Frame Packet is
received without CRC error.
This bit is updated after every Start of Frame packet receipt.
Important note: the Start of Frame interrupt is generated just after the PID receipt.
Frame Number CRC Error
This bit is set by hardware when a corrupted Frame Number in Start of Frame packet is
received.
This bit is updated after every Start of Frame packet receipt.
Important note: the Start of Frame interrupt is generated just after the PID receipt.
Reserved
The value read from this bit is always 0. Do not set this bit.
Frame Number
FNUM[10:8] are the upper 3 bits of the 11-bit Frame Number (see the
UFNUML (S:BAh, read-only) USB Frame Number Low Register” on page
provided in the last received SOF packet (see SOFINT in the
(S:BEh) USB Global Interrupt Enable Register” on page
corrupted SOF is received.
