23 Reserved, must be cleared.
22 Data pulse interrupt status. Indicates when data bus pulsing occurs on DP or DM. Data bus pulsing only detected
DPIS when USBMODE[CM] equals 11 and PORTSC0[PP] is cleared. Software must write a 1 to clear this bit.
21 1 millisecond timer interrupt status. This bit is set once every millisecond. Software must write a 1 to clear this bit.
1MSS
20 B session end interrupt status. Indicates when VBUS falls below the B session end threshold. Software must write
BSEIS a 1 to clear this bit.
19 B session valid interrupt status. Indicates when VBUS rises above or falls below the B session valid threshold (0.8
BSVIS VDC). Software must write a 1 to clear this bit.
18 A session valid interrupt status. Indicates when VBUS rises above or falls below the A session valid threshold (0.8
ASVIS VDC). Software must write a 1 to clear this bit.
17 A VBUS valid interrupt status. Indicates when VBUS rises above or falls below the VBUS valid threshold (4.4
AVVIS VDC) on an A device. Software must write a 1 to clear this bit.
16 USB ID interrupt status. Indicates when a change on the ID input is detected. Software must write a 1 to clear this
IDIS bit.
15 Reserved, must be cleared.
14 Data bus pulsing status.
DPS 0 No pulsing on port.
1 Pulsing detected on port.
