I have a simple sketch for selecting audio inputs that works perfectly with a Nano Classic. I am trying to get it to work on a Nano Every and am getting the following errors:
C:\Users\fortr\Documents\Arduino\Input-NanoV2\Input-NanoV2.ino: In function 'void setup()':
C:\Users\fortr\Documents\Arduino\Input-NanoV2\Input-NanoV2.ino:49:1: error: 'PCICR' was not declared in this scope
PCICR = 0b00000010; //PCIE1: pin Change interrupt Enable 1
^~~~~
C:\Users\fortr\Documents\Arduino\Input-NanoV2\Input-NanoV2.ino:50:1: error: 'PCMSK1' was not declared in this scope
PCMSK1 = 0b00000011; //Enable PIN Change Interrupt for A0 and A1
^~~~~~
exit status 1
Compilation error: 'PCICR' was not declared in this scope
Here is the actual code:

I did not write the code and am not familiar with this programming. Any ideas?
