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

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