Class USART.DataRegister

java.lang.Object
  extended byavrora.sim.RWRegister
      extended byavrora.sim.mcu.USART.DataRegister
All Implemented Interfaces:
ActiveRegister
Enclosing class:
USART

protected class USART.DataRegister
extends RWRegister

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 Detail

write

public void write(byte val)
Description copied from class: RWRegister
The 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.

Specified by:
write in interface ActiveRegister
Overrides:
write in class RWRegister
Parameters:
val - the value to write

writeBit

public void writeBit(int bit,
                     boolean val)
Description copied from class: RWRegister
The writeBit() method writes a single bit value into the IO register at the specified bit offset. For simple RWRegister instances, this simply updates the bit in the internally stored value

Specified by:
writeBit in interface ActiveRegister
Overrides:
writeBit in class RWRegister
Parameters:
bit - the number of the bit to write
val - the value of the bit to write

read

public byte read()
Description copied from class: RWRegister
The read() method reads the 8-bit value of the IO register as a byte. For simple RWRegister instances, this simply returns the internally stored value.

Specified by:
read in interface ActiveRegister
Overrides:
read in class RWRegister
Returns:
the value of the register as a byte

readBit

public boolean readBit(int bit)
Description copied from class: RWRegister
The readBit() method reads a single bit from the IO register.

Specified by:
readBit in interface ActiveRegister
Overrides:
readBit in class RWRegister
Parameters:
bit - the number of the bit to read
Returns:
the value of the bit as a boolean
