+title: Mobileye EyeQ5 pin controller
+
+description: >
+  The EyeQ5 pin controller handles the two pin banks of the system. It belongs
+  to a system-controller block called OLB.
+
+  Pin control is about bias (pull-down, pull-up), drive strength and muxing. Pin
+  muxing supports two functions for each pin: first is GPIO, second is
+  pin-dependent.
+
+  Pins and groups are bijective.
