POWER AND GROUND
All power pins should be connected to a single
connected to a common 0V ground supply Bypassing and filtering requirements are given in a separate User Information

SPECIAL CONNECT PINS
These are pins that have special connection requirements
No Connect (N C) pins should not be connected to anything This means not to power not to ground and not to each other
Reserved 0 (RES 0) pins must be connected to ground These pins are not used to supply device power so they do not need
to be filtered or bypassed
Reserved 1 (RES 1) pins must be connected to power These pins are not used to supply device power so they do not need
to be filtered or bypassed
