RE: [AVR-Chat] ATMega1284p External Interrupt 2 Setup

Sorry for talking to myself so much :-)   ...

I placed "uint8_t test = EICRA;" after setting EICRA and "test" did have the
expected 0x20 in it ... but AVR Studio still shows the EICRA as 0x00 so I
think I've confirmed that the Dragon or AVR Studio has a problem ...

My Interrupt still doesn't work but at least the EICRA is set correctly but
first I'll get the scope out to be sure that the pin is actually changing
(driven by an MCP2515 CAN controller).

Sorry for the false alarm(s) ...
 
Cheers,

Chuck Hackett
