The Pin Designer has the X3 connector bus defined, but no apparent iMX7_Function pins assigned. Is this really an extension of the internal iMX7 address/bus or something user defined?
I’m looking for a group of pins that are treated as a single register I can write to, such as the 16-bit data bus on X3.
If not, how do I group gpio together to be written as a single 8 or 16-bit register. Is there a double-buffering approach or grouping mechanism?
