PIC12F683 Config Problems
Now I have a problem im trying to configure the oscillator and the MCLR using assembly code in PB. the code I have is:
@ __CONFIG _INTOSCIO & _MCLRE_ON
Now what am I missing. Plus I get an error:
Overwriting Previous Address Contents (2007)
Im not sure if this is write at all im using a my electronics teachers example for a different model pic. But on this pic there is only one Configure Word with the address (2007h). Any help would be appreciated.
REGISTER 12-1: CONFIG – CONFIGURATION WORD (ADDRESS: 2007h)
Note: Address 2007h is beyond the user
program memory space. It belongs to the
special configuration memory space
(2000h-3FFFh), which can be accessed
only during programming. See
“PIC12F6XX/16F6XX Memory Programming
Specification” (DS41204) for more
information.
