Subtest 02 Sin Wave
This subtest is executed by loading the COM file (ADSIN.COM). The program

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.
When the subtest is executed, the following message appears:
....Press test number[1-4] ? pause
