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
bit 7
UTEYE:
USB Eye-Pattern Test Enable bit
1
= Eye-Pattern Test is enabled
0
= Eye-Pattern Test is disabled
bit 6
UOEMON:
USB OE Monitor Enable bit
1
= OE signal is active; it indicates intervals during which the D+/D- lines are driving
0
= OE signal is inactive
bit 5
Unimplemented:
Read as ‘0’
bit 4
USBSIDL:
Stop in Idle Mode bit
1
= Discontinue module operation when the device enters Idle mode
0
= Continue module operation when the device enters 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.
