Config Bits and Reading/Writing
Posted: 05 Feb 2021 18:40
Hello,
I have a few different IC's that have config bit options like WDT, Oscillator Timer, etc
Ex. PIC16C62A or ST7FMC2S4T
Usually I just grab a working system and read the ICs and then simply save them for future instances where a processor may've taken damage.
When that time comes, how do I know that the CONFIG bits will be written to the new future IC's properly?
Do I need to do something when reading my initial master IC so that the original CONFIG bits will be a part of the IntelHex file?
If I simply copy the prog memory and then program that to new IC's, the unit will not run properly if those config bits are different, most likely.
Appreciate your wisdom and thank you in advance!
