Hello,
Could someone please explain me how to disable clockout feature on 12F675?
Below is my fuse setting
========================================
#fuses INTRC,NOWDT,NOPROTECT,NOMCLR,PUT,BROWNOUT
#use DELAY(clock=4000000)
I need to use RA4 as general output pin, however it sends out a clock.
Thanks a lot in advance

Look near the start of the 12F675.H file. It shows the CCS fuse
parameters for that PIC:
| Code: | //////// Fuses: LP,XT,HS,EC_IO,NOWDT,WDT,CPD,NOCPD,PROTECT,NOPROTECT,NOMCLR
//////// Fuses: MCLR,PUT,NOPUT,INTRC_IO,INTRC,RC_IO,RC,BROWNOUT,NOBROWNOUT |
The one you want is INTRC_IO, which stands for Internal RC oscillator
with I/O function.
The CCS fuse parameters are not completely obvious, but once you learn
how to read them, it's not hard to choose the correct one. |

If ever you're unsure what will get programmed into your #fuse bits, this is what I do.
(Assuming you're using MPLAB)
1. Compile the program under the MPLAB environment.
2. Go to the pulldown menu on top:
Configure-> Configuration Bits....
After each compile, then these bits in MPLAB get automatically updated. Thus you can verify after each compile. |
