**     Method      :  Cpu_Delay100US (bean MC9S08QE8_32)
**
**     Description :
**         This method realizes software delay. The length of delay
**         is at least 100 microsecond multiply input parameter
**         [us100]. As the delay implementation is not based on real
**         clock, the delay time may be increased by interrupt
**         service routines processed during the delay. The method
**         is independent on selected speed mode.
**     Parameters  :
**         NAME            - DESCRIPTION
**         us100           - Number of 100 us delay repetitions.
