IESM - SPI Specification?

The IESM Product Technical Specification (PTS), WA_DEV_Fastrk_PTS_001, Revision 001, 5th June 2007 says,

Unlike I2C, I don’t think there is any specific document that specifies the “standard” SPI bus :question:

So, what document does the panel suggest to get the best description of “SPI” as implemented by Wavecom? :question: :question:

(for a start, most “standard” SPI devices seem to name their data signals “MOSI” and “MISO” - but Wavecom use “I” and “IO”… :angry: )
