detection interrupt bit

Not used

0: No interrupt request issued

1: Interrupt request issued

This bit is set to “1” when detecting a bus-disconnect

state (2.5

µs or more of SE0) on a downstream port 1 in

DSCONN1 = “1”.

“0” can be set by software, but “1” cannot be set.

0: No interrupt request issued

1: Interrupt request issued

This bit is set to “1” when detecting a bus-connect

state (2.5

µs or more of J- or K- state) on a downstream

port 1 in DSCONN1 = “0”.

“0” can be set by software, but “1” cannot be set.

0: No interrupt request issued

1: Interrupt request issued

This bit is set to “1” when an error occurs on a

downstream port 1.

“0” can be set by software, but “1” cannot be set.

0: No interrupt request issued

1: Interrupt request issued

This bit is set to “1” when detecting a resume signal

on a downstream port 1 in the condition of HUB

suspended or port suspended state.

“0” can be set by software, but “1” cannot be set.

0: No interrupt request issued

1: Interrupt request issued

This bit is set to “1” when detecting a bus-change of a

downstream port 1 in the condition of HUB suspended

state. It is also “1” in the internal clock halted.

“0” can be set by software, but “1” cannot be set.

Write “0” when writing.

“0” is read when reading.
