(1) EM1-D512 sends the command to Power Management IC by SPI Interface. The contents of the command are as
follows. Core power supply (V) voltage is changed to 0.75 from 1.2V. PLL power supply (VA1/2/3) is stopped.
(2) Power Management IC changes the Core power supply (V) to 0.75V from 1.2V in at least 2 ms later and stops PLL
power supply (VA1/2/3). EM1-D512 does the preparations to transfer to the DeepSleep state between (1) and (2).
(3) Core power supply (V) voltage is changed to 1.2V from 0.75V. VPLL power supply (VA1/2/3) is supplied.
(4) GIO_P0 signal rising and inside PLL begins to oscillate. EM1-D512 is transit of state from DeepSleep to Normal
after inside PLL stable.
