Note 1: TPOR = Power-on Reset delay (10 s nominal).
2: T
STARTUP = TVREG (10 s nominal when VREGS = 1 and when VREGS = 0; depends upon
WUTSEL<1:0> bits setting).
3: T
RST = Internal State Reset time (32 s nominal).
4: TOST = Oscillator Start-up Timer. A 10-bit counter counts 1024 oscillator periods before releasing the
oscillator clock to the system.
5: T
LOCK = PLL lock time.
6: T
FRC and TLPRC = RC Oscillator start-up times.
7: If Two-speed Start-up is enabled, regardless of the primary oscillator selected, the device starts with FRC
so the system clock delay is just T
FRC, and in such cases, FRC start-up time is valid. It switches to the
primary oscillator after its respective clock delay.
