Question: PICs with two configuration words versus one, e.g., 16F88 versus 12F683
Please show me how to organize the configuration bits for PICs with more than one configuration word in the same format that they can be organized for PICs with a single configuration word. There are two code samples: one is for a 12F683 and the configuration bits are organized the way I like to see them; the second is for a 16F88 and the configuration bits are in a long string, but I would like to know how to organize them like they are organized in the 12F683 file. Thanks

Tracecom, Either way is acceptable, There are 2 configuration words for the F88 processor. There are even more for some of the higher end processors. I don't understand the question?

Thanks for the response. I know that both ways work, but I want to use the same style layout for the 16F88 as for the 12F683. I have tried several times to rearrange the 16F88 configuration in a vertical list instead of a long horizontal string, but can't get it to compile.
