• The unused input pins must be connected to the GND (0V) level if there is no individual note in the above table.
• The unused output pins must be left open (No connection) if there is no individual note in the above table.
• The unused input/output pins must be connected to the GND (0V) or power supply pin for I/O block with internal
• Same voltage level must be supplied to DV DD , AV DD 1, AV DD 2, XV DD , VV DD 2 and VV DD 3 power supply
• This IC is not reset only by making the RESB pin “Low”.
• The “Analog Source” unused pins (9 pin to 16 pin) must be connected to the GND (0V) level through the input
pull down resistor OFF or be left open with internal pull down resistor ON when input pin mode or must be left
open (No connection) when output pin mode if there is no individual note in the above table.
When you connect an I/O pin which is an input pin with internal pull-down resistor OFF at reset mode to the GND
or power supply level, we recommend you to use pull-down resistor or pull-up resistor individually as fail-safe.
