SPI signals

Hi,

looking for an information that I could'nt read from specs :

Is the nSS_SPI signal from the CON4 (GPG2) connector  an output or Input?
IF I want to drive the SPI signals correctly do I have to sent to nSS :
 0 + message + 1 

or does it gives me this sequence already ? (via the linux driver)

thx for your answers

nnSS_SPI is output bacause you are master so you driver SS pin. If you use
some spi driver or spidev driver it's done automatically you don't need to
change SS level.

thx
