This bit is set to “1” when any one of DP1 interrupt
source register’s bits at least is set to “1”.
This bit is cleared to “0” by clearing DP1 interrupt
source register to “0016”.
Writing to this bit causes no state change.
This bit is set to “1” when any one of DP2 interrupt
source register’s bits at least is set to “1”.
This bit is cleared to “0” by clearing DP2 interrupt
source register to “0016”.
Writing to this bit causes no state change.
Write “0” when writing.
“0” is read when reading.
0 : Remote-wakeup being not output
1 : Remote-wakeup being output
This bit change is not for a interrupt source.
When detecting 2.5
s or more of K-signal on a
downstream port in Hub-suspended state, K-signal is
output on from a upstream port and this bit is
simultaneously set to “1”.
“0” can be set by software, but “1” cannot be set.
