CYCLE COUNTS,   on TS201s EZ-LITE

I am using a TS201s-EZLITE kit.  I am attempting to time some code.  I expected number of processor clocks to be returned but I appear to be only getting ~10K tics per second.   My wallclock time as measured by watch is approximatley 4 seconds.   I have measured this loop three ways:

1) CYCLES_START method has ~38000 cycles

2) START_CYCLES_COUNT method  has ~45000 cycles

3) clock() method  has strange results

 

I have set the -DDO_CYCLE_COUNTS in the ProjectOptions->Compile->general->additional options

 

I have attached code.   Any help is appreciated.

 

Thanks,

Patrick
