Ground (0 V)*

Note:

*:

The same power supply voltage must be provided to every VCC pin, and the same GND

voltage level must be provided to every VSS pin.

For improved signal integrity, it is recommended to connect the VSS* pins, pin 13 and pin 32,

to GND: the pins are electrically connected to internal GND.
