Electrical Parameters
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 following events:
1. Hardware reset: the falling edge of a short ESR0 pulse and the moment when the first user instruction has
entered the CPU and its processing starts, if the ESR0 pulse is shorter than
SCU_RSTCNTCON.RELSA × T_FPI.
If the ESR0 pulse is longer than SCU_RSTCNTCON.RELSA × T_FPI, only the time beyond should be added to
the boot time (ESR0 falling edge to first user instruction).
2. Software reset: the moment of starting the software reset and the moment when the first user instruction
has entered the CPU and its processing starts
