Class Timer16Bit

java.lang.Object
  avrora.sim.mcu.AtmelInternalDevice
      avrora.sim.mcu.Timer16Bit

Direct Known Subclasses:

ATMegaFamily.Timer1, ATMegaFamily.Timer3

public abstract class Timer16Bit

extends AtmelInternalDevice

The Timer16Bit class emulates the functionality and behavior of a 16-bit timer on the Atmega128. 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	Timer16Bit.BufferedRegister In PWN modes, writes to the OCRnx registers are buffered.
protected class	Timer16Bit.OCRnxPairedRegister The normal 16-bit read behavior described in the doc for PairedRegister does not apply for the OCRnx registers.
protected class	Timer16Bit.OCRnxTempHighRegister See doc for OCRnxPairedRegister.
protected class	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	Timer16Bit.TCNTnRegister Overloads the write behavior of this class of register in order to implement compare match blocking for one timer period.
protected class	Timer16Bit.Ticker The Ticker implements the periodic behavior of the timer.
