Note
① For the unused pins:
• The unused input pins must be connected to the GND (0 V) level
• The unused output pins must be leave open (No connection)
• The unused input/output pins must be connected to the GND (0 V) or power supply pin for I/O in input pin mode or must be left open (No connection) in
output pin mode
② NC pins must be left open
③ For power supply pins:
• Same voltage must be supplied to DVDD, AVDD, XVDD, LRVDD, VVDD1, VVDD3 power supply pins (Refer to allowable operating ranges)
④ MODE pin must be connected to the DVDD
⑤ TEST pins must be connected to GND (0 V)
⑥ During power-on, RESB pin must be set to "Low" for more than 20 ms
