The table about the SPI Modes is wrong for modes 2 and 3. Additionally i suggest to add a column on the clock edge for the data capture (takeover) of the client device.

Existing (wrong) table:

Mode	Clock Polarity (CPOL)	Clock Phase (CPHA)	Output Edge
SPI_MODE0	0	0	Falling
SPI_MODE1	0	1	Rising
SPI_MODE2	1	0	Falling
SPI_MODE3	1	1	Rising

I suggest to replace the table by this (modified cell content in bold):

Mode	Clock Polarity (CPOL)	Clock Phase (CPHA)	Output Edge	Data Capture
SPI_MODE0	0	0	Falling	Rising
SPI_MODE1	0	1	Rising	Falling
SPI_MODE2	1	0	Rising	Falling
SPI_MODE3	1	1	Falling	Rising

Done thank you!

Thanks
Unfortunately there is a small spelling mistake on the web page (marked in bold below)

Mode	Clock Polarity (CPOL)	Clock Phase (CPHA)	Output Edge	Data Capture
SPI_MODE0	0	0	Falling	Rising
SPI_MODE1	0	1	Rising	Falling
SPI_MODE2	1	0	Rising	Flling
SPI_MODE3	1	1	Falling	Rising

Fixed sorry for that
