Subtest 02	Sin Wave
	This subtest is executed by loading the COM file (ADSIN.COM). The
	program expands sin wave data table from 16KB to 64KB, and creates the
	play data. Then it transfers the data between the DMA and the CODEC to
	play the sine wave. (It sounds like a continuous beep). By using wave
	measuring devices such as an oscilloscope, the data can be measured as a sine
	wave.

	....Press test number[1-4] ? pause

	from 16KB to 64KB data and is beeped.
