Hi,

I am planning a PCB using the ATtiny441.

To program the ATtiny441 later I want to use the ISP interface.

Now looking into the datasheet I found that I can change the SPI pins (MISO, MOSI, SCK) default locations to alternate locations.

For example I can change the MISO pin location from its default pin PA5 to the alternative pin PA0

But because this configuration is done at run time, instead of using fuses, I assume ISP is only available on the default locations?

Correct.
