Just a simple question. Should the WL_REG_ON pin of CYW4343W be driven to VDDIO or VBAT to enable WiFi? I think its VDDIO, however its not 100% clear to me from the data sheet that this is correct. Just looking for confirmation on that. Thanks.

Hello:

It is VDDIO,  and mostly it will be connected to the HOST GPIO to  control the on and off.

Thanks for the reply. BTW I meant regulator not register.
