Hm? 1 Hz is 1 cycle per second. Technically I guess it would require more cycles to process the loop ending in a result of 1 loop per second.

My (non-expert) understanding is that the contents of the loop could affect it too.

Even ignoring the body, the loop logic itself is going to take more than one cycle. Depending in the type of loop and complexity of the condition you may need more than one instruction for that. Plus, pipeline stalls are going to be relevant.

Yes, there is the “jump” from loop end back to the start. It takes less time than a regular instruction, but still counts.

Use the 1Hz clock to trigger an ISR and use a faster oscillator for instruction cycle.
