Power and Ground Pins
The pins described in Table 18 provide system power and ground to the chip. Multiple pins are provided for adequate current
capability. All power supply pins must have adequate bypass capacitance for high-frequency noise suppression.
Some of the VDD and VSS pins on the device are only to be used for noise bypass. Figure 5 shows a typical connection diagram.
Pay particular attention to those pins which show only capacitor connections. Do not connect power supply voltage directly to
these pins.
