LTC4300A-2 ACC-pin termination


We need minimize circuit with LTC4300A-2.

ACC pin pull-up or pull-down resistor is necessary?

(Mode is ACC disable. Pull-down to GND)

In LTC4300A-2 datasheet, ACC-pin is CMOC input logic.

I guess pull-down resistor is not nessesary.

Circuit examples in datasheet are both case.

Do they use for different purposes?(about pull-up resistor R10.)

Best regards 

Thank you very much
