Note 1: TPOR = Power-on Reset delay.
2: TPWRT = 64 ms nominal if regulator is disabled (ENVREG tied to VSS).
3: TFRC and TLPRC = RC Oscillator start-up times.
4: TLOCK = PLL lock time.
5: TOST = Oscillator Start-up Timer (OST). A 10-bit counter waits 1024 oscillator periods before releasing
oscillator clock to the system.
6: If Two-Speed Start-up is enabled, regardless of the Primary Oscillator selected, the device starts with
FRC, and in such cases, FRC start-up time is valid.
Note: For detailed operating frequency and timing specifications, see Section 29.0 “Electrical Characteristics”.
