+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.
