LTC2640 SPI mode (CPOL and CPHA)

I've been reading the LTC2640 datasheet, but it doesn't give a clue about which SPI mode should be used. In other words, it doesn't tell me about CPOL and CPHA. The timing diagram is not helpful in that respect, though it seems to suggest that the clock idles high.


So, what CPOL and CPHA should I use?


Kind regards, Samuel Lourenço
