Each pin can be set to “0”, “1” or “f” (floating). 1 ~ 6 1 ~ 6 A6/D5, A7/D4 A8/D3 ~ A11/D0 I Code Address Pin Nos.6 ~ 11/Data Pin Nos.5 ~ 0. These six tri-state pins are detected by PT2262 to determine the encoded waveform bit 6 ~ bit 11. When these pins are used as address pins, they can be set to “0”, “1”, or “f” (floating). When these pins are used as data pins, they can be set only to “0” or “1”. 7, 8 10 ~ 13 7, 8 12 ~ 15 /TE I Transmission Enable. Active Low Signal. PT2262 outputs the encoded waveform to DOUT when this pin is pulled to low. 14 16 OSC1 O Oscillator Pin No.1 15 17 OSC2 I Oscillator Pin No.2 A resistor connected between these two pins determine the fundamental frequency of the PT2262. 16 18 DOUT O Data Output Pin. The encoded waveform is serially outputted to this pin. When PT2262 is not transmitting, DOUT outputs low (Vss) voltage. 17 19 Vcc - Positive Power Supply 18 20 Vss - Negative Power Supply 9 9 |
