Yes exactly, in this case it's just a matter of multiplying the value you get with 0.5 to get the answer in uS.

If you want to do that in PBP then perhaps:
Code:
' In us
LCDOUT $FE, 1, ["Timer ticks: ", DEC Time]
LCDOUT $FE, $C0, ["Execution time: ", DEC Time/2, "." DEC Time//2, "us",13]
I think that should do it.
