Table 19. Power and Ground Pins
Dedicated power supply signals to isolate the sensitive PLL analog
circuitry from the normal levels of noise present on the digital power
supply.
These pins supply positive power to the I/O pads
These pins supply positive power to the core logic.
This pin is the negative supply (ground) to the chip.
