Reserved, VCC
These pins are reserved by Intel and may have factory test functions. For
normal operation, connect them directly to VCC. Do not connect them to
pull-up resistors.
Reserved, Ground
These pins are reserved by Intel and may have factory test functions. For
normal operation, connect them directly to ground. Do not connect them to
pull-down resistors.
Reserved, No Connect
These pins are reserved by Intel and may have factory test functions. For
normal operation, do not connect any circuitry to these pins. Do not connect
pull-up or pull-down resistors.
No Connect
