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 31-8 Unimplemented: Read as ‘0’
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
bit 5
Unimplemented: Read as ‘0’
bit 4
USBSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
bit 3-1
Unimplemented: Read as ‘0’
bit 0
UASUSPND: Automatic Suspend Enable bit
1 = USB module automatically suspends upon entry to Sleep mode. See the USUSPEND bit
0 = USB module does not automatically suspend upon entry to Sleep mode. Software must use the
USUSPEND bit (U1PWRC<1>) to suspend the module, including the USB 48 MHz clock
