Class PicIndfReg

java.lang.Object
  hades.models.pic.PicIndfReg

All Implemented Interfaces:

PicReg

public class PicIndfReg

extends java.lang.Object

implements PicReg

PicIndfReg - Register for indirect addressing, if indf itself is addressed indirect then a shadow-register will be used to prevent recursive dead - actually this shadow-register is not a real register, it is implemented as a PicNoReg with no functionality

Field Summary

PicNoReg	byte0
PicWordReg	fsr
PicReg[]	reg
PicByteReg	status

Constructor Summary

PicIndfReg(PicBreakPoint newBp, PicWordReg newFsr, PicByteReg newStatus, PicReg[] newReg)

Method Summary

protected PicReg	findSource()
boolean	getBit(int selectedBit) test a specified bit
int	getBreakPoint() Get BreakPoint returns the value that has been set by setBreakPoint
int	getSize() How many bits are accessable with read() and write() ?
int	getSizeAll() How many bits are accessable with readAll() and writeAll() ?
void	por() Power-on-reset
int	read() Read the normal content of the register
int	readAll() Read the extended content of the register
void	reset() Normal reset, often this will be the same as por()
void	setBit(int selectedBit, boolean newValue) set a specified bit
void	setBreakPoint(int value) Set BreakPoint: value >= 0 : break if content equals value value = -1 : no breakpoint value = -2 : break if content has changed
protected void	testBreakPoint()
void	write(int newValue) write a new value into the register
void	writeAll(int newValue) Write the extended content of the register
