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.
