I'm using a C8051F330 and I need to time some code. My Performance
Analyzer is greyed out and I can therefor not use it. I also saw this
which says there is a "secs" item in the registers window, but I do
not see it. I'm using Keil uVision4.72.9.
you will not get a real time from the performance analyzer, it
will get mixed up on SILabs instruction timing vs 'plain vanilla'
use the C2, start a timer at the beginning of the code you want to
check, set a breakpoint at the exit and read the timer
