Communicate With Your Module

I/O messages are sent to (consumed) and received from (produced) 
the I/O modules. These messages are mapped into the processor’s 
memory.   The  32  point  valve  driver  produces  1  byte  of  input  data 
(scanner  Rx  -  status),  and  consumes  1  byte  of  I/O  data  (scanner 
Tx).
