The nop instruction adds 1 instruction, maybe you can just adjust the
loop counter so it's effectively the same as before.

But I wouldn't worry about it too much. The counter cannot be higher
than 1024, and this is quite a low delay so making it a bit longer with
a nop should have a noticeable impact.

Best regards.
