PIC12F675 triso question?

[Gruntus]

Good day all
I'm pretty new to the fancy PIC world and I feel that I'm understanding most of what I'm reading. One of the things that is confusing me is triso.
For the PIC12F675 I have seen example code with triso=%00000000 and
triso=%000000
The code I'm playing with has outputs on gpio.0 and gpio.1, the rest are digital inputs.
Would triso=%111100 be correct or am I missing the way 1's and 0's work.

Thanks
