Legend: U = Unimplemented bit, read as ‘0’
R = Readable bit W = Writable bit HSC = Hardware Settable/Clearable bit
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-8 Unimplemented: Read as ‘0’
bit 7 ID: ID Pin State Indicator bit
1 = No plug is attached, or a type B cable has been plugged into the USB receptacle
0 = A type A plug has been plugged into the USB receptacle
bit 6 Unimplemented: Read as ‘0’
bit 5 LSTATE: Line State Stable Indicator bit
1 = The USB line state (as defined by SE0 and JSTATE) has been stable for the previous 1 ms
0 = The USB line state has NOT been stable for the previous 1 ms
bit 4 Unimplemented: Read as ‘0’
bit 3 SESVD: Session Valid Indicator bit
1 =The V
BUS voltage is above VA_SESS_VLD (as defined in the USB OTG Specification) on the A or
B-device
0 =The VBUS voltage is below VA_SESS_VLD on the A or B-device
bit 2 SESEND: B-Session End Indicator bit
1 =The VBUS voltage is below VB_SESS_END (as defined in the USB OTG Specification) on the
B-device
0 =The V
BUS voltage is above VB_SESS_END on the B-device
bit 1 Unimplemented: Read as ‘0’
bit 0 VBUSVD: A-V
BUS Valid Indicator bit
1 =The VBUS voltage is above VA_VBUS_VLD (as defined in the USB OTG Specification) on the
A-device
0 =The V
BUS voltage is below VA_VBUS_VLD on the A-device
