Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-29 Unimplemented: Read as ‘0’
bit 28-24
NAKLIM<4:0>: Endpoint 0 NAK Limit bits
The number of frames/microframes (Hi-Speed transfers) after which Endpoint 0 should time-out on receiving
a stream of NAK responses.
bit 23-22
SPEED<1:0>: Operating Speed Control bits
11 = Low-Speed
10 = Full-Speed
01 = Hi-Speed
00 = Reserved
bit 21-7 Unimplemented: Read as ‘0’
bit 6-0
RXCNT<6:0>: Receive Count bits
The number of received data bytes in the Endpoint 0 FIFO. The value returned changes as the contents of
the FIFO change and is only valid while RXPKTRDY is set.
