Where did you get that part?  It looks to me as though the timing  
diagrams in Figure 2-2 and example 2-1 look exactly like the similar  
diagrams (3-3 and 3-1) from the pic10f manual, and the 'block diagram'  
looks identical compared to the 16F506...
(hmm.  Except for 64x8 of "flash data memory.")
