If you want a descripion that tells you that ......GPIO.0 will start up as an analogue comparator input pin .... or whatever, you're in bad luck. No such table, you'll have to write your own. The clostest one is Table 3-1(page 24) , that table lists all register associated with GPIO, it also lists their POR("default") values. From there you need to check each register separatley, to see how the individual bits affect each pin on your Pic.
