java.lang.Object
  avrora.sim.State.RWIOReg
      avrora.sim.mcu.ATMega128L.SimImpl.USART.DataRegister

All Implemented Interfaces:

State.IOReg

Enclosing class:

ATMega128L.SimImpl.USART

protected class ATMega128L.SimImpl.USART.DataRegister

extends State.RWIOReg

The DataRegister class represents a Transmit Data Buffer Register for a USART. It is really two registers, a transmit register and a receive register. The transmit register is the destination of data written to the register at this address. The receive register is the source of data read from this address.

Method Summary

byte	read() The read() method reads the 8-bit value of the IO register as a byte.
boolean	readBit(int bit) The readBit() method reads a single bit from the IO register.
void	write(byte val) The write() method writes an 8-bit value to the IO register as a byte.
void	writeBit(int bit, boolean val) The writeBit() method writes a single bit value into the IO register at the specified bit offset.

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

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

read

public byte read()

Description copied from class: State.RWIOReg

The read() method reads the 8-bit value of the IO register as a byte. For simple RWIOReg instances, this simply returns the internally stored value.

Specified by:

read in interface State.IOReg

Overrides:

read in class State.RWIOReg

Returns:

the value of the register as a byte

readBit

public boolean readBit(int bit)

Description copied from class: State.RWIOReg

The readBit() method reads a single bit from the IO register.

Specified by:

readBit in interface State.IOReg

Overrides:

readBit in class State.RWIOReg

Parameters:

bit - the number of the bit to read

Returns:

the value of the bit as a boolean
