    Default Help with pic16c771

    I've compiled and programmed a PICBASIC PRO program for the pic16c771, but apparently, nothing runs.

    I suspect that I may not have the correct oscillator selected (internal RC 4MHz) and possibly the MCLR pin is configured for reset. According to the manual the register that configures these, and other bits, is the configuration word. However, this is not accessible since it is at address 2007H.

    You can find this information in section 12 of the pic16c771 manual @

    Any ideas as to what to do??

    Are there PICBASIC PRO defines or other commands to configure this word??

    Thanks,

    John

    Which version of PBP are you using?
