2	WGR	A/D Conversion, Waveform Generator Reload
	AD	The function of this bit depends on the EPA channel.
		For EPA capture/compare channels 0, 2, 4:
		The WGR bit allows you to use the EPA activities to cause the reload of
		new values in the waveform generator.
		0 = no action
		1 = enables waveform generator reload
		For EPA capture/compare channels 1, 3, 5:
		The AD bit allows you to use the EPA activities to start an A/D
		conversion that has been previously set up in the A/D control registers.
		0 = causes no A/D action
		1 = starts an A/D conversion on an output compare
1	ROT	Reset Opposite Timer
		Selects the timer that is to be reset if the RT bit is set.
		0 = selects the reference timer for possible reset
		1 = selects the opposite timer for possible reset
		The state of the TB bit determines which timer is the reference timer and
		which timer is the opposite timer.
0	RT	Reset Timer
		This bit controls whether the timer selected by the ROT bit will be reset.
		1 = resets the timer selected by the ROT bit
		0 = disables the reset function
