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
s or more of SE0) on a downstream port 2 in
DSCONN2 = “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
s or more of J- or K- state) on a downstream
port 2 in DSCONN2 = “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 2.
“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 2 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 2 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.
