Legend: WC = Write ‘1’ to clear HS = Hardware Settable bit
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 IDIF: ID State Change Indicator bit
1 = Change in ID state detected
0 = No change in ID state detected
bit 6 T1MSECIF: 1 Millisecond Timer bit
1 = 1 millisecond timer has expired
0 = 1 millisecond timer has not expired
bit 5 LSTATEIF: Line State Stable Indicator bit
1 = USB line state has been stable for 1 ms, but different from last time
0 = USB line state has not been stable for 1 ms
bit 4 ACTVIF: Bus Activity Indicator bit
1 = Activity on the D+, D-, ID or VBUS pins has caused the device to wake-up
0 = Activity has not been detected
bit 3 SESVDIF: Session Valid Change Indicator bit
1 =V
BUS voltage has dropped below the session end level
0 =V
BUS voltage has not dropped below the session end level
bit 2 SESENDIF: B-Device V
BUS Change Indicator bit
1 = A change on the session end input was detected
0 = No change on the session end input was detected
bit 1 Unimplemented: Read as ‘0
bit 0 VBUSVDIF: A-Device VBUS Change Indicator bit
1 = Change on the session valid input detected
0 = No change on the session valid input detected
