Configuration word

Nick · Guest

Hi,
I am writing a program for PIC12F629 and I haven't understand which
C instruction use to write the configuration word. I can set it only from IDE menu, but i want to write it with a C instruction because MPLAB IDE doesn't visualize GP3 flag.

Thanks,

Nick

Look for #fuses in the help file and also look at the header file for the PIC you have selected.

I have already looked for in included files and help file and there aren't any references about configuration bits.

The #fuse statement is used to set the configuration bits. By looking at the header file, you can see what options are available.

I think there is no way to control the special register and configuration bits in CCS compiler. All you can do is use its built-in function. The hearder file only include the parameter for built-in function and I/O port parameter:)

My problem is that bit 5 of configuration word select MCLR pin function:
if bit is 1 pin function is MCLR else if bit is 0 pin function is the alternate function (so I think it means pin works as a classic I/O pin) and MCLR is internally disabled.

Thank you for help

I solved my problem with #fuses directive.
