Class PicRegBank

java.lang.Object
  hades.models.pic.PicRegBank

All Implemented Interfaces:

PicMemory

Direct Known Subclasses:

PicRegBank16F84

public class PicRegBank

extends java.lang.Object

implements PicMemory

PicRegBank - 512 8-bit-registers, organized in 4 banks including all special registers. The PIC16C84 only implements some of these registers, see documentation. The complexity of this class is high due to the memory-mapped architecture of the PIC-family. Remember this when you try to understand the code...
