Description
Code Address Pin Nos. 0 ~ 7
These eight tri-state pins are detected by PT2260 to
determine the encoded waveform bit 0 ~ bit 7. Each bit can
be set to “0”, “1”, or “f” (floating).
Code Address Pin No. 8 ~ 9/Data Pin No. 3 ~ 2.
These two tri-state pins are detected by PT2260 to
determine the encoded waveform bit 8 ~ bit 9. When these
pins are used as address pins (as in PT2260-R2), they can
be set to “0”, “1”, or “f” (floating). When these pins are used
as data pins (as in PT2260-R4), they can only be set to “0”
or “1”.
Data Pin No. 1/0.
These pins can only be set to “0” or “1”
Oscillator Pin
A resistor connected between the Osc Pin and the Vcc
determines the fundamental frequency of the PT2260
Data Output Pin.
The encoded waveform is serially outputted to this pin.
When PT2260 is not transmitting, DOUT outputs low (Vss)

Note:
PL -- Pull-low Resistor is connected internally
PL* -- If those two pins are used as Data Pins (PT2260-R2), pull-low resistor is connected internally;
otherwise, no pull-low resistor is connected.
