Playing mode :EDGEL/LEVEL , HOLD/UNHOLD , RETRIGGER/IRRETRIGGER with following mask options :
C>IO1(VDD-edge.GND-level)
D>IO2(VDD-edge.GND-level)
E>IO3(VDD-edge.GND-level)
C, D, E could only be selected when IO1,IO2,IO3 are mask_option as control input .

Item_F : 0.75Hz or 1.5Hz or 3Hz or 6Hz(mask option)
Item_B~I : with one subtable enable status option for IO1, IO2, IO3.
COUT : 3 current output levels, with 4 mask options (1.5mA;3mA;4.5mA;IO3<GND-3mA,VDD-4.5mA>).
PWM1, PWM2 : must be selected on the same time ,direct driving buzzer or 8 or 32 or 64 ohm speaker.
STOPH, STOPL : 40 ms high/low output when device stop playing.(drive 1.8 mA,sink 10mA;3v).
BUSYH, BUSYL : high/low output during device playing (drive 1.8 mA,sink 10mA;3v).
6Hz/3Hz, DYNA1/4, 2/4, 3/4 : LED driving. (drive 1.8 mA, sink 10mA;3v)
Used as control input : internal pull GND (0.5uA,3V)
For all the IO options : the dynamic should choice same level.
If IO2 and IO3 are both at 6Hz(3Hz), they will flash alternatively.
When used as control input, they could be used to control following options by bonding or toggle switch.
