"I/O Combination mode 1" IO0~IO7 always keep the corresponding level after Outputting corresponding level. The difference between "I/O Combination mode 0"and "I/O Combination mode 1"is that it still plays music when IOs restore to original high level in "I/O Combination mode 0", and it stops playing music when IOs restore to original high level in "I/O Combination mode 1" The difference between "I/O stand-alone mode 0" and "I/O stand-alone mode 1"is the same as above 4£®Module size 5. Modes operation instructions 5.1 I/O Combination mode 0 MCU I/O output corresponding level to trigger specified music and release the IO level to high, it stops playing music after completing playing current music; It will play the new music, if retrigger the music while playing. If keep the triggering state, it will keep playing circularly. The busy pin is always effective while playing. 5.2 I/O Combination mode 1 MCU I/O output corresponding level to trigger specified music and keep the triggering state, it will keep playing circularly. It will stop playing immediately when release to original high level anytime. The busy pin is always effective while playing.
