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 15-8 Unimplemented: Read as ‘0’
bit 7-0 CNT<7:0>: Start of Frame Count bits
Value represents 10 + (packet size of n bytes); for example:
0100 1010 = 64-byte packet
0010 1010 = 32-byte packet
0001 0010 = 8-byte packet

bit 7 UTEYE: USB Eye Pattern Test Enable bit
1 = Eye pattern test enabled
0 = Eye pattern test disabled
bit 6 UOEMON: USB OE
Monitor Enable bit
1 =OE
signal active; it indicates intervals during which the D+/D- lines are driving
0 =
OE signal inactive
(1)
bit 5 Unimplemented: Read as ‘0’
bit 4 USBSIDL: USB OTG Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
bit 3-0 Unimplemented: Read as ‘0’
Note 1: When the UTRIS (UxCNFG2<0>) bit is set, the OE signal is active regardless of the setting of UOEMON.
