Possible to use SB6 (Wi-Fi module) in AT mode with SPI I/O?

I am trying to determine if it possible to use SPI as an input/output method for the SB6 wi-fi module when in Transparent (AT) mode.

I remember seeing a post somewhere on the internet that suggested that it does work, contrary to the manual (which states that SPI is only available in API mode), but I can’t seem to find that post now that I’m experimenting with the Xbee boards.

Before I throw in the towel and assume that what I read about this working is incorrect, I thought I’d ask the experts.

Thank you for your help.

Per the manual, the SPI port require the use of API mode.
