SEL_SLAVE selects MODE1 (STAND ALONE MODE) or MODE 2/3 (SLAVE MODE).
By selecting SEL_SLAVE, SLAVE mode terminal setting shown in Table II.2 is enabled.
SEL_SLAVE is set only at power ON. Note that change of selection after power ON is ignored.
MPEG Audio Layer 1, 2, 3 play selection signal
SEL_MP3 allows you to select the layer of the MPEG audio to be played. When enabling all the files having mp1,
mp2 or mp3 as the file extension to be played, enter L. When enabling mp3 only, enter H.
