Field Detail

maskRegister

public ATMegaFamily.MaskRegister maskRegister

mapping

protected final int[] mapping

The mapping array maps a bit number (0-7) to an interrupt number (0-35). This is used for calculating the posted interrupts.

interruptMask

protected final long interruptMask

public ATMegaFamily.FlagRegister(int[] map)

Method Detail

write

public void write(byte val)

Description copied from class: State.RWIOReg

The write() method writes an 8-bit value to the IO register as a byte. For simple RWIOReg instances, this simply writes the internally stored value.

Specified by:

write in interface State.IOReg

Overrides:

write in class State.RWIOReg

Parameters:

val - the value to write

flagBit

public void flagBit(int bit)

writeBit

public void writeBit(int bit,
                     boolean val)

Description copied from interface: State.IOReg

The writeBit() method writes a single bit value into the IO register at the specified bit offset.

Specified by:

writeBit in interface State.IOReg

Overrides:

writeBit in class State.RWIOReg

update

public void update(avrora.sim.mcu.ATMegaFamily.IMRReg other)

update

public void update(int bit,
                   avrora.sim.mcu.ATMegaFamily.IMRReg other)

getVectorNum

protected int getVectorNum(int bit)
