FAQ/023 KAM-500: What is the difference between DNC (Do not connect) and NC (Not connected) as a pin description in KAM-500 data sheets?
August 18, 2014
NC means the pin is not connected to the module.
DNC is used for two reasons:
- The pins are reserved and may be used in a later revision.
- The pins could be undocumented inputs or outputs for internal test purposes or reserved for a customer-specific requirement.
It is important to follow the instruction and not connect the pin.
