About t is Document:
The RS9110-N-11-02 is an 02.11n single-stream module with built-in
MAC/BBP, RF and PA, and front-end components. It interfaces to a host
processor through an SDIO or SPI interface. This document provides
information that may be used while integrating the module into an end
solution.

NOTE on SPI_CS and SPI_CLK: -
Based on the Host SPI configuration, during BOOT UP, SPI Master could be coming up as GPIO pins.In the wake of this possibility, it
may be needed to add a pull up on the SPI_CS and a pull up (CPOL=1)/pull down(CPOL=0) on the SPI_CLK. The value of pull up/ pull
down resistor should follow the recommendations as given on the HOST side.
