PIN CONFIGURATION

I/O
Description
Pin No.
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).
A0 ~ A7
I
1 ~ 8
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
A8/D3 ~ A9/D2 I/PL* pins are used as address pins (as in PT2260-R2), they can 10 ~ 11
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.

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.
