It's only SPI.
However a massive amount depends on what you actually want to 'do'?.
If you just want to control it (letting it store the data etc..), then the key is to get the 'design guide' (not the basic data sheet):
It uses Mode3 SPI. Max 1MHz.
The design guide even has a nice little flow chart to follow.
If you want to do anything much 'beyond' the equivalent to the button based commands, then you'd be better off with a larger PIC. You'll certainly need a larger memory connected to the PIC for anything beyond this.
