Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-8 Unimplemented: Read as ‘0’
bit 7 ID: ID Pin State Indicator bit
1 = No cable is attached or a type B cable has been plugged into the USB receptacle
0 = A “type A” OTG cable has been plugged into the USB receptacle
bit 6 Unimplemented: Read as ‘0’
bit 5 LSTATE: Line State Stable Indicator bit
1 = USB line state (SE0 bit (U1CON<6>) and JSTATE bit (U1CON<7>) has been stable for previous 1 ms
0 = USB line state (SE0 and JSTATE) has not been stable for previous 1 ms
bit 4 Unimplemented: Read as ‘0’
bit 3 SESVD: Session Valid Indicator bit
1 =V
BUS voltage is above Session Valid on the A or B device
0 =V
BUS voltage is below Session Valid on the A or B device
bit 2 SESEND: B-Device Session End Indicator bit
1 =VBUS voltage is below Session Valid on the B device
0 =VBUS voltage is above Session Valid on the B device
bit 1 Unimplemented: Read as ‘0’
bit 0 VBUSVD: A-Device V
BUS Valid Indicator bit
1 =V
BUS voltage is above Session Valid on the A device
0 =V
BUS voltage is below Session Valid on the A device
