All Implemented Interfaces:

State.IOReg

Enclosing class:

ATMega128L.SimImpl.USART

protected class ATMega128L.SimImpl.USART.ControlRegisterA

extends ATMegaFamily.FlagRegister

UCSRnA (ControlRegisterA) is one of three control/status registers for the USART. The high three bits are actually interrupt flag bits.

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 ATMegaFamily.FlagRegister

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 ATMegaFamily.FlagRegister

decode

protected void decode(byte val)
