W5100 Ethernet Shield

Hi Guys, I’m working on the W5100 ethernet shield from adruino and I was wondering what SPI mode does it use?
I have looked up the data sheet and found that the W5100 chip uses SPI modes (0,3)
Does this mean that it uses all 4 modes?

Thank you.


Arduino Ethernet shield use SPI to connect the W5100.
“SPI modes (0,3)” means W5100 only support SPI mode 0 and 3.
