(1) A_RESETB signal and DET1 signal are falling, and RTC clock (C32K) is stop. Next Core power supply and PLL
power supply are stopped at the same time.
(2) Core power supply (V) and PLL power supply (VA1/2/3) are supplied same time, and stand by until a power
supplies become stable.
(3) RTC clock 32.768kHz (C32K) is input.
GIO_P0 signal rising. It's to make EM1-D512 recognizes that it's different from "Without power supply".
(4) DET1 is signal is started.
(5) A_RESETB signal rising (reset release), and inside PLL begins to oscillate.
