1) The duration of the boot time is defined between the rising edge of the internal application reset and the clock cycle when
the first user instruction has entered the CPU pipeline and its processing starts.
2) The timing values assumes programmed BMI with ESR0CNT inactive.
3) The duration of the boot time is defined by all external supply voltages are inside there operation condictions and the clock
cycle when the first user instruction has entered the CPU pipeline and its processing starts.
