TPS548D22: RESV_TRK pin

Part Number: TPS548D22

Hi

On the datasheet, the RESV_TRK pin is not connected.

However there is a capacitor at RESV_TRK pin.(It is DNP.)

Please let me know if there is any concerns without a capacitor.

(Which is better? with a capacitor or without a capacitor.)

On the application note, the capacitor is connected.
