     31== Processor Pin Mux DevMem Example
     32Let's for example say we would like to modify a pin-mux register on a i.MX8 processor. Utilizing the reference manual for the processor (available from the processor manufacturer) we see we need to use devmem to write the value 101 (0x5 in hex) to the proper register.
