Usual Minimum Prepared Time calculation?

[jazbaatbadalgaye]

How is the following statement evaluated to 100ms?

uint32_t UsualMinimumPreparedTime = StepTimer::StepClockRate/10;				// 100ms

If the step clock rate is 1MHz (1000000), the step clock time should be 10^-6 sec, hence the UsualMinimumPreparedTime should evaluate to 10^-5 sec i.e. 0.01 ms or 10us. Am I missing something?
