I would like some information on configuring Port E0 to be a clock output of 4Mhz. Is their an example someplace.

// configures CPU clock @4 MHz

CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);

(, , );

(

);

Hi brazov,

I am not sure but I think that the HSI oscillator is set to 16 MHz so we need to do the following config in order to output 4 MHz on CCO pin:

CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV4);

instead of

CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);

What do you think ? Regards, MCU Lüfter

yes for sure, it was a typo error
