Do Not Connect.
Do not connect any of these pins to supply, ground or any other
signal. Internal pull-ups or pull-downs will prevent any of these pins
from floating.

Epad
T_GND
G
Thermal Paddle.
This pad is connected to GND internally. The pad can be con-
nected to GND externally or it can be left open-circuit and used as
a thermal input to the on-chip temperature sensor.
*Note: G = Ground, S = Power Supply, I = Digital Input, O = Digital Output, I/O = Input/Output.
