+#### PD_RST
+
+This is the PD_RST line to reset the STUSB4500 USB PD controller. You normally will not need to use this.
+
+There is a 10K hardware pull-down resistor on this pin. If you set the pin to OUTPUT and HIGH, it will reset the chip.
+
+#### PD_ALERT
+
+This is the PD_ALERT output from the STUSB4500 USB PD controller. 
+
+#### PD_ATTACH
+
+This is the PD_ATTACH output from the STUSB4500 USB PD controller.
