PIC24FJ128G010 CLock settings

[kareem ahmed]

The Data sheet says that this chip can do 16 MIPS @32Mhz, although I cant make it work @ 32Mhz

From MPLABX V2.26 and using C30, I generated these Config bits Value as follow :

 

 int CONFIG2 __attribute__((space(prog), address(0x157FC))) = 0xFB3E ;

 

//_CONFIG2(

//    POSCMOD_HS &         // Primary Oscillator Select (HS Oscillator mode selected)

//    OSCIOFNC_OFF &       // Primary Oscillator Output Function (OSC2/CLKO/RC15 functions as CLKO (FOSC/2))

//    FCKSM_CSECME &       // Clock Switching and Monitor (Clock switching is enabled, Fail-Safe Clock Monitor is enabled)

//    FNOSC_PRIPLL &       // Oscillator Select (Primary Oscillator with PLL module (HSPLL, ECPLL))

//    IESO_ON              // Internal External Switch Over Mode (IESO mode (Two-Speed Start-up) enabled)

//);

 

Now I know that my controller is not working @ 32Mhz as I mesaured the clock on RC15 and found 8Mhz, Hence is working @16Mhz !

 

So my Question is , what I am missing ?? How to Make it work @ 32Mhz !!
