Note: "Button Combined Playback" Refers to the Restoration of the Original High Level after the Corresponding Level Is Output at IO0-IO7, Similar to the One Triggered at Button.
"Level Combination Playback" Means That the Level Remains Unchanged after IO0-IO7 Outputs the Corresponding Level.
The Difference between "I/O Combination (Independent) Mode 0" and "I/O Combination (Independent) Mode 1" Is That the Former Mode Releases the Level and Continues to Play the Current Track until the End, the Latter Mode Stops Playing Immediately after Releasing the Level.
