NS7520 wireless hardware manual

I’m developing with with Connect WiME in Netos7.3 and I’m trying to determine exactly when the WiME acknowledges the receipt of a segment. I’m not sure if this is automatically handled in hardware and how much processing must be done with the packet before the WiME responds with an ack.

I need to locate more information about the wireless driver. Does anyone know where I can locate documenation for the wireless driver configuration registers? The NS7520 Hardware Reference manual only refers to the Ethernet Front End register mappings and has no information about the wireless register mappings or am I missing something here? Thanks for any info.
