Config bits - fuses in 16f8**

[PIC2PIC]

Hi !
Is there some nice text that explains about all fuses for PIC 16f8** and what for are they used.

 

[3v0]

The processor data sheet should have a section on the config register(s). It will explain what each bit does.

Hi 3vO
Thank you for your help. Still I consider that explanation from data sheet shows very little. For instance, I don't know what LVP or Brown-out Reset Enable is. Data sheet shows where is it and how to enable/disable the bit but don't tell what the exact fuse is used for. I know some, for instance I know what WDT is for but not all others.

LVP is Low Voltage Programming. And Brown-out is for if the pic gets a lower voltage supply than it needs, it resets.

Here I did this today for some one else But read the data sheet to make sure there mostly the same but read yours and use this to see what you set


The data sheet tell you starting at bit 0 you want
0 at bit 0 Oscillator Selection bits
0 at bit 1 Oscillator Selection bits
0 at bit 2 0 = WDT disabled
0 at bit 3 0 = PWRT enabled
1 at bit 4 Oscillator Selection bits
0 at bit 5 0 = RA5/MCLR/VPP pin function is digital Input, MCLR internally tied to VDD
0 at bit 6 0 = BOR Reset disabled a 1 if you need this
0 at bit 7 0 = RB4/PGM is digital I/O, HV on MCLR must be used for programming++
1 at bit 8 1 = Data memory code protection off you sure want this a 1
0 at bit 9 Unimplemented: Read as ‘0’
0 at bit 10 Unimplemented: Read as ‘0’
0 at bit 11 Unimplemented: Read as ‘0’
0 at bit 12 Unimplemented: Read as ‘0’
1 at bit 13 1 = Code protection off

But if you can i would set it like this

__CONFIG _CP_OFF & _WDT_OFF & _BODEN_OFF & _PWRTE_ON & _RC_OSC & _WRT_OFF & _LVP_ON & _CPD_OFF

Less chance of setting wrong this way
