Legend:
R = Readable bit
-n = Value at POR
HS = Hardware Settable bit
W = Writable bit
‘1’ = Bit is set
HC = Hardware Clearable bit
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 1
bit 0
Unimplemented: Read as ‘0’
UACTPND: USB Activity Pending bit
1 = Module should not be suspended at the moment (requires USLPGRD bit to be set)
0 = Module may be suspended or powered down
Unimplemented: Read as ‘0’
USLPGRD: Sleep/Suspend Guard bit
1 = Indicate to the USB module that it is about to be suspended or powered down
0 = No suspend
Unimplemented: Read as ‘0’
USUSPND: USB Suspend Mode Enable bit
1 = USB OTG module is in Suspend mode; USB clock is gated and the transceiver is placed in a
low-power state
0 = Normal USB OTG operation
USBPWR: USB Operation Enable bit
1 = USB OTG module is enabled
0 = USB OTG module is disabled⁽¹⁾
Note 1: Do not clear this bit unless the HOSTEN, USBEN and OTGEN bits (U1CON<3,0> and U1OTGCON<2>)
are all cleared.
