Note: 1.PU = Internal pull up, PD = Internal pull down.
2.A 0.1-μF bypass capacitor should be placed as close as possible to each positive power pin (<0.2”). If these bypass capacitors are not close to the
pins their high frequency filtering characteristics will be cancelled by the lead inductance of the traces.
3.AVDD and VDD pins must be connected to a power supply level that is at least equal or higher than that of VDDQA, VDDQB, VDDQC, and VDDFB
power supply pins
