EM7455 CONFIG_x Pin Assignment

I am trying to design a PCB to interface with the EM7455 Module, and the datasheet lists 4 ‘CONFIG_’ pins on the host interface pin assignments table.

All of these pins are ‘reserved’ and specified as outputs - does this mean they should all be left not connected?

The confusion is coming from CONFIG_3 and CONFIG_2 stating ‘NC in default module configuration’, but CONFIG_0 and CONFIG_1 say ‘GND in default module configuration’. I assume this means what they are connected to internally, and not that I have to connect CONFIG_0 and CONFIG_1 to GND externally - is that correct?

you can leave all the CONFIG_x pin open
