NOTE:
1: “Key combination play”: Return to the original high level after the corresponding level from I/O0 – I/O7 output, similar to the key triggered once. Similar instantaneous switch.
2: “Level combination play”: The trigger signal remains similar to a self-locking switch.
2: The difference between “I/O integrated/independent mode 0” and “I/O integrated/independent mode 1” – Mode 0 will continue playing the current song to the end after the release level, and Mode 1 will stop playing immediately after the release level.
I/O Integrated Mode 0 (key combination playing)
NOTE: the song must be named for 5bit.

It will stop playing the current song to the end after I/O0-7 releases the input signal (return to high) at ‘I/O Integrated Mode 0’. It will play a new song when receiving a new input signal while playing a song and stop after the end of the song. It will repeatedly play if the signal is kept. Busy pin output HIGH signal during playing. Music control following.
