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’
JSTATE: Live Differential Receiver J State Flag bit
1 = J state (differential ‘0’ in low speed, differential ‘1’ in full speed) detected on the USB
0 = No J state detected
SE0: Live Single-Ended Zero Flag bit
1 = Single-ended zero active on the USB bus
0 = No single-ended zero detected
TOKBUSY: Token Busy Status bit
1 = Token being executed by the USB module in On-The-Go state
0 = No token being executed
RESET: Module Reset bit
1 = USB Reset has been generated; for software Reset, application must set this bit for 10 ms, then
clear it
0 = USB Reset terminated
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; software must set bit for 10 ms and then clear to enable remote wake-up
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
SOFEN: Start-Of-Frame Enable bit
1 = Start-Of-Frame token sent every one 1 millisecond
0 = Start-Of-Frame token disabled
