The status of push-switches SW2 to SW5 determines the value of S1V30080 standalone 1
SET_PLAY[3:0]. The value is "0" when pressed, and "1" when released. For example, to play back
file index number 4, press SW5, SW3, and SW2.
DIP switch SW6 acts as an auxiliary function, allowing the pin corresponding to SET_PLAY[3:0]
to be set to "0" while SW6 is set to "On." The correlation between SW6 and SET_PLAY[3:0] is
shown in Table 3.7. Push-switches SW2 to SW5 can be used for control when it is off.
