ISOW7740: Need to add PU on EN-Pin (Pin-8)?

Part Number: ISOW7740

Hi,

just to be clear on my side:

I do not need the /FLT function but want to enable the DC/DC at all times.

Do I need to connect Pin-8 (EN/ \FLT) to VIO (Pin 1) with a Pullup or not?

Figure 9.5 in Datasheet claims there already is a PU to VIO (550k)

I would like to leave Pin-8 open.

EN-IO1 and EN-IO2 can be open to enable Input/ Output-ports and they have 550k PU (internal) as well.

Thanks

Mathias
