Constructor Detail

### ATMega128L.SimImpl.PinRegister

    protected ATMega128L.SimImpl.PinRegister(ATMega128L.Pin[] p)

Method Detail

### read

    public byte read()

  Description copied from interface: `State.IOReg`
  The `read()` method reads the 8-bit value of the IO register as a byte. For special IO registers, this may cause some action like device activity, or the actual value of the register may need to be fetched or computed.

  Specified by:
    `read` in interface `State.IOReg`
  Returns:
    the value of the register as a byte

### readBit

    public boolean readBit(int bit)

  Description copied from interface: `State.IOReg`
  The `readBit()` method reads a single bit from the IO register.

  Specified by:
    `readBit` in interface `State.IOReg`
  Parameters:
    `bit` - the number of the bit to read
  Returns:
    the value of the bit as a boolean

### write

    public void write(byte val)

  Description copied from interface: `State.IOReg`
  The `write()` method writes an 8-bit value to the IO register as a byte. For special IO registers, this may cause some action like device activity, masking/unmasking of interrupts, etc.

  Specified by:
    `write` in interface `State.IOReg`
  Parameters:
    `val` - the value to write

### writeBit

    public void writeBit(int num,
                         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`
  Parameters:
    `num` - the number of the bit to write
    `val` - the value of the bit to write
