bit 1
Reserved: Write ‘0’; ignore read
IDIF: ID State Change Indicator bit
Write a ‘1’ to this bit to clear the interrupt.
1 = Change in ID state detected
0 = No change in ID state detected
T1MSECIF: 1 Millisecond Timer bit
Write a ‘1’ to this bit to clear the interrupt.
1 = 1 millisecond timer has expired
0 = 1 millisecond timer has not expired
LSTATEIF: Line State Stable Indicator bit
Write a ‘1’ to this bit to clear the interrupt.
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
ACTVIF: Bus Activity Indicator bit
Write a ‘1’ to this bit to clear the interrupt.
1 = Activity on the D+, D-, ID, or VBUS pins has caused the device to wake-up
0 = Activity has not been detected
SESVDIF: Session Valid Change Indicator bit
Write a ‘1’ to this bit to clear the interrupt.
1 = VBUS voltage has dropped below the session end level
0 = VBUS voltage has not dropped below the session end level
SESENDIF: B-Device VBUS Change Indicator bit
Write a ‘1’ to this bit to clear the interrupt.
1 = A change on the session end input was detected
0 = No change on the session end input was detected
Reserved: Write ‘0’; ignore read
