java.lang.Object avrora.sim.RWRegister avrora.sim.mcu.USART.DataRegister
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.

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