Class ATMega128L.SimImpl.Timer16Bit

java.lang.Object
  avrora.sim.mcu.ATMega128L.SimImpl.Timer16Bit

Direct Known Subclasses:

ATMega128L.SimImpl.Timer1, ATMega128L.SimImpl.Timer3

Enclosing class:

ATMega128L.SimImpl

protected abstract class ATMega128L.SimImpl.Timer16Bit

extends java.lang.Object

The Timer16Bit class emulates the functionality and behavior of a 16-bit timer on the Atmega128L. It has several control and data registers and can fire up to six different interrupts depending on the mode that it has been put into. It has three output compare units and one input capture unit. UNIMPLEMENTED: input capture unit.

Nested Class Summary

protected class	ATMega128L.SimImpl.Timer16Bit.BufferedRegister In PWN modes, writes to the OCRnx registers are buffered.
protected class	ATMega128L.SimImpl.Timer16Bit.ControlRegister ControlRegister is an abstract class describing the control registers of a 16-bit timer.
protected class	ATMega128L.SimImpl.Timer16Bit.ControlRegisterA ControlRegisterA describes the TCCRnA control register associated with a 160bit timer.
protected class	ATMega128L.SimImpl.Timer16Bit.ControlRegisterB ControlRegisterA describes the TCCRnB control register associated with a 160bit timer.
protected class	ATMega128L.SimImpl.Timer16Bit.ControlRegisterC ControlRegisterA describes the TCCRnA control register associated with a 16-bit timer.
protected class	ATMega128L.SimImpl.Timer16Bit.OCRnxPairedRegister The normal 16-bit read behavior described in the doc for PairedRegister does not apply for the OCRnx registers.
protected class	ATMega128L.SimImpl.Timer16Bit.OCRnxTempHighRegister See doc for OCRnxPairedRegister.
protected class	ATMega128L.SimImpl.Timer16Bit.PairedRegister The PairedRegister class exists to implement the shared temporary register for the high byte of the 16-bit registers corresponding to a 16-bit timer.
protected class	ATMega128L.SimImpl.Timer16Bit.TCNTnRegister Overloads the write behavior of this class of register in order to implement compare match blocking for one timer period.
protected class	ATMega128L.SimImpl.Timer16Bit.Ticker The Ticker implements the periodic behavior of the timer.
