Notes :
The AVD and PLLVDD should be separated on the board.
Insert a bypass capacitor with a superior high-frequency characteristic between the power
supply and ground. Place the capacitor as near the pins as possible.
: Ground
: 3.3 V power supply
: 2.5 V power supply
: Analog power supply
: PLL power supply
: Internal DRAM power supply
: Do not connect anything.
: Input the low level.
: Input the high level.
: Input the high level.
