Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-8 Unimplemented: Read as ‘0’

bit 7 JSTATE: Live Differential Receiver JSTATE flag bit

1 = JSTATE detected on the USB

0 = No JSTATE detected

bit 6 SE0: Live Single-Ended Zero flag bit

1 = Single Ended Zero detected on the USB

0 = No Single Ended Zero detected

bit 5 PKTDIS: Packet Transfer Disable bit(4)

1 = Token and packet processing disabled (set upon SETUP token received)

0 = Token and packet processing enabled

TOKBUSY: Token Busy Indicator bit(1,5)

1 = Token being executed by the USB module

0 = No token being executed

bit 4 USBRST: Module Reset bit(5)

1 = USB reset generated

0 = USB reset terminated

bit 3 HOSTEN: Host Mode Enable bit(2)

1 = USB host capability enabled

0 = USB host capability disabled

bit 2 RESUME: RESUME Signaling Enable bit(3)

1 = RESUME signaling activated

0 = RESUME signaling disabled

Software is required to check this bit before issuing another token command to the U1TOK register (see

Register 10-15).

All host control logic is reset any time that the value of this bit is toggled.

Software must set RESUME for 10 ms if the part is a function, or for 25 ms if the part is a host, and then

clear it to enable remote wake-up. In Host mode, the USB module will append a low-speed EOP to the

RESUME signaling when this bit is cleared.

Device mode.

Host mode.
