Questions about fuses

[ViOleT]

Hi everyone, I am new to CCS. Can anybody show me links on information about fuses. I have done a search in this forum concerning fuses but they don't really give enough explanations. It just shows the meaning of the fuses, e.g., NOCPD - it stands for [No EE protection]. But what exactly does that mean ? When do we use it ? Are there links that have in-depth explanations of these fuses ? I hope anybody here can help me and guide me in the right direction. Thanks in advance.

Here's a Microchip tutorial on the Configuration Bits:

After the first few pages, it starts to explain them in more detail.


Also look in the "Special Features of the CPU" section in your PIC's
data sheet. It explains the Config Bits for your PIC.

Add one more 'comment', the 'meanings', are in the file 'fuses.txt', with your compiler. This gives 'longhand' phrases specifying what each abbreviation is for. What these phrases then actually 'mean' (in human terms), is then down to the data sheet.
Many of the fuses use 'ancestral' terms. So in the 'NOCPD' example given, the earliest PICs, with flash memory, and EEPROM, had fuses for 'NO Code Protect Data memory, and this became 'NOCPD'. Unfortunately, in some cases, MicroChip, has 'renamed' fuses in latter chips. CCS has tended to keep the old names, where they are for the same function, so you will sometimes find a CCS 'name', that doesn't agree with the MicroChip ne in the data sheet.
The key is to look at the data sheet for _your_ chip, make your own list of all the fuses and what they do, work out what ones you want, and then look up the CCS names fo these.
