SC5104 4. data out data code is output at dout. when one key is pressed, high level is output at pin led and data (four frames at least) is output at dout after 32ms delay. data is continuously output if t he key is kept pressed and there is 4 code interval between frames. 5. oscillator internal oscillator integrates advanced key-press start power saving function. the oscillator is in sleep mode when there is no key pressed and there is no current; it onl y works when key is pressed. this is for power saving. 455khz oscillator is connected to pins osci and osco for using. 6. key code table instruction code key no. d0 d1 d2 d3 d4 d5 d6 k1 0 0 0 0 0 0 1 k2 0 0 0 0 0 1 0 k3 0 0 0 0 1 0 0 k4 0 0 0 1 0 0 0 k5 0 0 1 0 0 0 0 k6 0 1 0 0 0 0 0 k7 1 0 0 0 0 1 1 k8 1 0 0 00 1 1 0 hangzhou silan microelectronics co.,ltd rev:1.2 2009.05.05 http: www.silan.com.cn page 4 of 8
