XIO2001: About pull-down at not used VDD_33_AUX

Hello,

Regarding to VDD_33_AUX on XIO2001, my customer is asking some question.

(Question)

(1) When VDD_33_AUX is not used, is external pull-down needed?

(2)If so, how much resistor value is needed?

(According to 9.2.1.1.3 Auxiliary Power(D/S page115), it is greater than 3kΩ.)

Do you have recommendation resistor value?

(They will use 3kΩ. It's OK?)

Regards,
