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 given time includes the time of the internal reset extension for a configured value of
SCU_RSTCNTCON.RELSA = 0x05BE.
3) The duration of the boot time is defined between the rising edge of the PORST and the clock cycle when the
first user instruction has entered the CPU pipeline and its processing starts.
4) The given time includes the internal reset extension time for the System and Application Reset which is visible
through ESR0.
