Features
y Operating voltage: 2.
4V~5.
0V y One single-key can implement play-all, play-next and random function.
Maximum play count is 32.
y 4-column inputs and 3-row outputs can implement 4x4-matrix function.
y Each input can implement looping function.
y Single-key and 4-column inputs can be last-key priority for stand-alone input or first-key priority.
y Each input trigger can select trigger mode: (For OKY, TG0, TG1, TG2, TG3) Edge/Level, Hold/Unhold, Retrigger/Irretrigger.
y Each input trigger can select its own debounce time: Fast debounce: < 200us; Slow debounce: ~16ms (S.
R.
