INT Flag
R
0 = RT disconnected, Rpd connected
1
1 = RT connected, Rpd disconnected
0 = RT disconnected, Rpd connected
1
1 = RT connected, Rpd disconnected
0 = RT disconnected, Rpd connected

1 = RT connected, Rpd disconnected
0 = Disconnected
0
1 = Connected
INT Flag B1b[1] is set by 5V_PortC edge signal when 5V_PortC
changes from 1 to 0, or from 0 to 1.
0 = Disconnected
0
1 = Connected
INT Flag B1b[1] is set by 5V_PortB edge signal when 5V_PortB
changes from 1 to 0, or from 0 to 1.
0 = Disconnected
1 = Connected
0
INT Flag B1b[1] is set by 5V_PortA edge signal when
5V_PortA changes from 1 to 0, or from 0 to 1
0 = INT Flag Clear
1 = INT Flag Set
INT Flag will be set from logic Low to High, when any 5V_Port has
0
detected plug or unplug transition action.
INT Flag is cleared to low after I²C bus reads the register byte 1.
See INT Flag flowchart.
0 = Passive switch
0
DDC channel selection
R/W
0
1 = Active switch buffer
For power saving operation, passive switch can be selected to fur-
ther reduce the active power consumption.
