Power on and Reset control
Attention when power on
The RESB pin must be set to “Low” level when power is first supplied. At that time, it is necessary to input a stable
clock to the XIN pin.
You may input the voltage of VDD or less to each input terminal when the power supply is off.

*1 : The oscillation must be stable during tRESW2.
When the XIN clock has been stopped by the command etc. , the specification of tRESW2 could be larger than
the value shown above, because it takes time that the XIN oscillator becomes stable.
