SPI mode for 25aa256 memory chip?

Can anyone tell me what the right "mode" is the the 25aa256 SPI eeprom. Looking at the data sheets, I'm thinking it should be mode 0, but I may be getting tangled up in the terminology and getting it backwards. The sample code I looked at all seems to be for mode 3.

Thanks!

Seems to me that both 0,0 = 0, and 1,1 = 3 are allowed.
