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
paly 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.
