16
IDIS
USB ID interrupt status
This bit is set when a change on the ID input has been detected.
Software must write a 1 to this bit to clear it.
0
R/WC
17
AVVIS
A-VBUS valid interrupt status
This bit is set then VBUS has either risen above or fallen below the
A-VBUS valid threshold (4.4 V on an A-device).
Software must write a 1 to this bit to clear it.
0
R/WC
18
ASVIS
A-Session valid interrupt status
This bit is set then VBUS has either risen above or fallen below the
A-session valid threshold (0.8 V).
Software must write a 1 to this bit to clear it.
0
R/WC
19
BSVIS
B-Session valid interrupt status
This bit is set then VBUS has either risen above or fallen below the
B-session valid threshold (0.8 V).
Software must write a 1 to this bit to clear it.
0
R/WC
20
BSEIS
B-Session end interrupt status
This bit is set then VBUS has fallen below the B-session end threshold.
Software must write a 1 to this bit to clear it.
0
R/WC
21
ms1S
1 millisecond timer interrupt status
This bit is set once every millisecond.
Software must write a 1 to this bit to clear it.
0
R/WC
22
DPIS
Data pulse interrupt status
This bit is set when data bus pulsing occurs on DP or DM. Data bus pulsing
is only detected when the CM bit in USBMODE = Host (11) and the
PortPower bit in PORTSC = Off (0).
Software must write a 1 to this bit to clear it.
