Interface Simulator.IORWatch

All Superinterfaces:

Simulator.Watch

All Known Implementing Classes:

MulticastIORWatch, Simulator.IORWatch.Empty

Enclosing interface:

Simulator

public static interface Simulator.IORWatch

extends Simulator.Watch

The IORWatch interface represents a user probe that is fired when a watchpoint detects an access to an IO register where the watch has been inserted. Direct as well as indirect accesses (through pointers) are monitored. Implicit accesses for special registers such as SPL, SPH, and SREG in push, pop, call, sei, etc instructions are NOT MONITORED. These instructions are syntactically apparent in the program and can be probed with Simulator.Probe instructions. This interface extends the Simulator.Watch interface with methods to trap reads and writes to individual bits within a register.

Nested Class Summary

static class

Simulator.IORWatch.Empty The Simulator.IORWatch.Empty class acts as a base class with empty methods for each fireXXX() method.

Method Summary

void	fireAfterBitRead(State state, int ioreg_num, int bit, boolean value) The fireAfterBitRead() method is called after the data address is read by the program.
void	fireAfterBitWrite(State state, int ioreg_num, int bit, boolean value) The fireAfterBitWrite() method is called after the data address is written by the program.
void	fireBeforeBitRead(State state, int ioreg_num, int bit) The fireBeforeBitRead() method is called before the data address is read by the program.
void	fireBeforeBitWrite(State state, int ioreg_num, int bit, boolean value) The fireBeforeBitWrite() method is called before the data address is written by the program.

Method Detail

fireBeforeBitRead

public void fireBeforeBitRead(State state,
                              int ioreg_num,
                              int bit)

The fireBeforeBitRead() method is called before the data address is read by the program.

Parameters:

state - the state of the simulation

ioreg_num - the number of the IO register being read

fireBeforeBitWrite

public void fireBeforeBitWrite(State state,
                               int ioreg_num,
                               int bit,
                               boolean value)

The fireBeforeBitWrite() method is called before the data address is written by the program.

Parameters:

state - the state of the simulation

ioreg_num - the number of the IO register being read

value - the value being written to the memory location

fireAfterBitRead

public void fireAfterBitRead(State state,
                             int ioreg_num,
                             int bit,
                             boolean value)

The fireAfterBitRead() method is called after the data address is read by the program.

Parameters:

state - the state of the simulation

ioreg_num - the number of the IO register being read

value - the value of the memory location being read

fireAfterBitWrite

public void fireAfterBitWrite(State state,
                              int ioreg_num,
                              int bit,
                              boolean value)

The fireAfterBitWrite() method is called after the data address is written by the program.

Parameters:

state - the state of the simulation

ioreg_num - the number of the IO register being read

value - the value being written to the memory location
