The Port Configuration Register controls the basic port functions including clock control and auxiliary

output port width.

NOTE

If the PCR register exists in a separate arbiter module at the SoC level in a

multi-Nexus environment, then the settings at the SoC level override the

settings in the A7S Nexus3 module.
