(5) Power Up sequence
(5-1) The sequence for power down mode after power-up.
Clock input to the CLKIN pin is necessary to guarantee “Current Consumption of Power down”
(r) : Register-bit
Rev-E-00
There are no order restriction to make power up, AVDD, DVDD, PVDD1, PVDD2.
Clock input is not necessary to write register.
Note.1) Please wait 100ns for make PDN pin low after the Voltage of Power Supply becomes stable enough,
