Hope you feel better soon funky mate.... 
Anyway....
The AS1130 runs completely independently once the microcontroller has told it what to do.
Basically, you set up the registers, upload the frame and PWM data and tell it to start...it then runs on it's own.
While it is running you can upload more data and it'll display that.
All this is explained in the first post of this thread along with the answer to all your other questions....
