Remarks “Stable” means that each power supply becomes the specification minimum voltage.
The timing figure which starts from the “Without power supply”.
(1) IO power supply (VIO18) is supplied, and stands by until a power supply becomes stable.
(2) IO power supply (VIO3) is supplied, and stands by until a power supply becomes stable.
(3) Corepower supply (V) and PLL power supply (VA1/2/3) are supplied, and stands by until a power supply becomes
stable.
(4) RTC clock 32.768kHz (C32K) is input.
(5) DET1 is signal is started.
(6) A_RESETB signal rising (reset release), and PLL begins to oscillate.
