GND—These pins provide grounding for the internal structures of the chip and
should all be attached to VSS.
Analog Ground—This pin supplies an analog ground.
TCS—This Schmitt pin is reserved for factory use and must be tied to VSS for
normal use. In block diagrams, this pin is considered an additional VSS.

VCAPC—Connect each pin to a 2.2uF or greater bypass
capacitor in order to bypass the core logic voltage regulator
(required for proper chip operation). For more information, please
refer to Section 5.2
VPP—This pin should be left unconnected as an open circuit for
normal functionality.
