I am going over the data sheet for a PIC12F629 controller again and see this note:
<b>When MCLR is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.</b>
Does this mean that if I set up the MCLR to have voltage at the pin instead of having it get voltage internally that the chip has no internal clock at all to operate on? I'd have to have an external oscillator to make things work?
I don't know yet if I have to have the MCLR pin powered for this project. I think there must be another internal clock that runs regardless to run the software and this probably isn't a concern?
I also am still struggling as to how I program these extra special feature bits. The data sheet says:
<b>Address 2007h is beyond the user program memory space. It belongs to the special configuration memory space (2000h - 3FFFh), which can be accessed only during programming. See PIC12F629/675 Programming Specification for more information.</b>
I don't find a "Programming Specification" section in the datasheet. I think I need to program at least some of the bits if I want 5 outputs and possibly the MCLR pin available. I do see in the programmer itself I can toggle all these features when I select the chip so I suppose this does the same thing as writing them in the code myself?
Thanks.
