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

bit 0
Unimplemented: Read as ‘0’
SE0: Live Single-Ended Zero Flag bit
1 = Single-ended zero is active on the USB bus
0 = No single-ended zero is detected
PKTDIS: Packet Transfer Disable bit
1 = SIE token and packet processing are disabled; automatically set when a SETUP token is received
0 = SIE token and packet processing are enabled
Unimplemented: Read as ‘0’
HOSTEN: USB Host Mode Enable bit⁽¹⁾
1 = USB host capability is enabled; pull-downs on D+ and D- are activated in hardware
0 = USB host capability is disabled
RESUME: USB Resume Signaling Enable bit
1 = Resume signaling is activated
0 = Resume signaling is disabled
PPBRST: Ping-Pong Buffers Reset bit
1 = Resets all Ping-Pong Buffer Pointers to the EVEN buffer descriptor banks
0 = Ping-Pong Buffer Pointers are not reset
USBEN: USB Module Enable bit
1 = USB module and supporting circuitry are enabled (device attached); D+ pull-up is activated in hardware
0 = USB module and supporting circuitry are disabled (device detached)
Note 1: This bit should be ‘0’ in Device mode.
