Electrical Parameters
2) t_OSCS is defined from the moment when V_DDOSC3 = 3.13 V until the oscillations reach an amplitude at XTAL1 of
0,3 × V_DDOSC3. This parameter is verified by device characterization. The external oscillator circuitry must be
optimized by the customer and checked for negative resistance as recommended and specified by crystal
suppliers.
3) Any ESR0 activation is internally prolonged to SCU_RSTCNTCON.RELSA FPI bus clock (f_FPI) cycles.
4) Applicable for input pins TESTMODE and TRST.
5) f_FPI = f_CPU / 2
6) Not subject to production test, verified by design / characterization.
7) This parameter includes the delay of the analog spike filter in the PORST pad.
8) The duration of the boot-time is defined between the rising edge of the PORST and the moment when the first
user instruction has entered the CPU and its processing starts.
9) 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.
10) The given time includes the time of the internal reset extension for a configured value of
SCU_RSTCNTCON.RELSA = 0x05BE.
