(1)

LVCMOS pins are all I/O pins powered by DVDD, DVDD_GPMC, DVDD_GPMCB, DVDD_SD, DVDD_C supplies except for I2C[0] and

I2C[1] pins.

(2)

When using the internal Oscillators, the oscillator grounds (VSSA_DEVOSC, VSSA_AUXOSC) must be kept separate from other

grounds and connected directly to the crystal load capacitor ground.
