CD1030 ESD(Contact Discharge) 8kV condition?

Hi NXP community, may I ask the contact discharge spec about CD1030.

I notice that, WAKE_B contact discharge at 8kV level, a series 10k Ohms resistor is needed. Shown below.

I would like to know, whether the 10K Ohms resistor is the pull-up 10k Ohms resistor to VDDQ(Case 1 shown below), or an another series resistor(Case 2 shown below) for ESD test?

Case 1:

Hi Ellen,

I think case one Vbatp is a global signal. Maybe Vbatp originated out of the PCB. It would need the series resistor for ESD protection. In this case the resistor is used for both pull up and ESD protection.

WAKE_B as a global pin, 10k series resistor is needed. WAKE_B as a local pin, no 10k series resistor is needed.
