note1）The resistance precision is ±3 % (including thermal-characteristic)
note2）The capacitance precision is ±50 % (including thermal-characteristic)
note3）Connect them near the pin.
note4）Keep off them from clock line(noise source) and so on.
note5）When not using a power on reset, it is unnecessary, connecting.
note6) Be careful that the voltage of the LED_R/G/B-pin doesn't exceed "LVDD+0.3V" , by
the influence of the overshoot. In case of ,the overshoot is big and the LED wiring
is long, put a capacitor between " the LED_R/G/B terminal " and the grand.
