ATTiny2313 AY-3-8912 emulator
Is it possible to emulate AY-3-8912 PSG only with ATTiny2313 microcontroller?
The answer is yes, it is.
I made only serial interface because I don't have intention to use it as replacement for real AY-3-8192 integrated circuit, although also that would be possible.
Serial port settings: 115200,8,N,1,N
The data is sent in RV pairs where R is the register and V is the value to be
written into register.
