1.3 PC Data Mapping Considerations
This section describes data mapping, and suggests a mapping technique you can use in
programming or configuring PCs and in configuring the PC interface. The technique is intended
to optimize the utilization of memory and avoid problems that can make a PC layout inefficient.
In addition, the assigning of CCF channel numbers in the PC interface is described to show the
