7.8 SPI Microcontroller Interface AC Characteristics
7.8.1: Each AV DD , PV DD and DV DD power supply must be turned on and off at the same timing.
7.8.2: XMODE must be fixed to “H” before power is turned on in order to use the power-on reset function.
7.8.3: SI has to set to “L” input when turning the power on.
