These six tri-state pins are detected by PT2272 to determine the encoded waveform bit 0 ~ bit 5. Each pin can be set to “0”, “1”, or “f” (floating). 1 ~ 6 1 ~ 6 A6/D5 ~ A11/D0 I/O Code Address Pin Nos. 6 ~ 11/Data Pin Nos. 5 ~ 0. These six pins are used as higher address input bits or data output pins depending on the version (type) of PT2272 used. When used as address inputs, these pins are tri-state input pins and each pin can be set to “0”, “1”, or “f” (floating). When used as output pins, these pins are driven to VCC if (1) the address decoded from the waveform that was received matches the address setting at the address input pins, and (2) the corresponding data bits received is a “1” bit. Otherwise, they are driven to VSS. 7 ~ 8 10 ~ 13 7 ~ 8 12 ~ 15 DIN I Data Input Pin. The encoded waveform received is serially fed to PT2272 at this pin. 14 16 OSC 1 I Oscillator Pin No.1 A resistor connected between these two pins determine the 15 17 OSC 2 O Oscillator Pin No. 2 fundamental frequency of PT2272. 16 18 VT O Valid Transmission. Active High Signal. VT in high state signifies that PT2272 receives valid transmission waveform. 17 19 VCC - Positive Power Supply 18 20 VSS - Negative Power Supply 9 9 NC - No Connection - 10 ~ 11 |
