Connection for port 1 detection and classification. See DET4 for detailed descrip-
tion.
Active low digital reset. Short to RST pin 23.
Port 1 power FET switch output. When on, provides a low impedance path to
VEE1.
Active low interrupt output pin.
Connect the thermal pad to a plane which connects to Vee. For best results, use a
5 x 5 or larger via array for best thermal conductivity with 1 square inch or larger
of plane area per device.
