Need help with config

[Darrenmac]

I am trying to set up internal asc and MCLr options in the config of my code for a 16f688. The data sheet has the config bits for all of this on page 100. Is there an easy way of setting this? I tried config=%11001111000100 nut this did not work. I got a syntax error. The posts that I have read seem to set each function in the config individualy. Can some one point me in the right direction.
Thanks

Hi,

I may have mis-understood your post but if you're just trying to set the configuration bits try:

for PM Assembler:

@ device INT_OSC, MCLR_OFF

Is this what you're after?

Kind regards

Rob

Yeah, that's a good thread - should've posted a link to it myself!

I have read the suggested post again. All examples in this post appear to set each option in the config seperatly, ie pic type, mclr, pwrt as seperate comands but the datasheet for the 16f688 shows a config register called 11.1 (page 100) with each option as seperate bits either set or cleared. Can I just send this as a binary string (or hex equivelent)? if so how?

It never worked that way for me, every newbie reads that and tries it,(I did) and it has never worked that I heard of. You can string the commands together though, like so:

@ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN_ON & _LVP_OFF & _CP_ALL & _DATA_CP_ON

The data sheet shows you what happens in those registers, but you can access them only at program time and require you to use the proper syntax as shown in Melanies post.
