Description
Code Address Pin Nos.0 ~ 5
These six tri-state pins are detected by PT2262 to
determine the encoded waveform bit 0 ~ bit 5.
Each pin can be set to “0”, “1” or “f” (floating).
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”.
Transmission Enable.
Active Low Signal. PT2262 outputs the encoded
waveform to DOUT when this pin is pulled to low.
A resistor connected
Oscillator Pin No.1
between these two pins
determine the fundamental
Oscillator Pin No.2
frequency of the PT2262.
Data Output Pin.
The encoded waveform is serially outputted to this
pin. When PT2262 is not transmitting, DOUT
outputs low (Vss) voltage.
