    Default Fuses pic 16F722

    Hi, I'am trying to understand the config fuses for the pic 16F722.

    I have the folowing settings (generated with the great fuse configurator tool)
    Code:
    Device = 16F722
    
    
    Config1 FOSC_INTOSCIO, WDTE_OFF, PWRTE_OFF, MCLRE_OFF, CP_OFF, BOREN_OFF, BORV_19, PLLEN_ON, DEBUG_OFF
    Config2 VCAPEN_DIS
    ;**** End of Fuse Configurator Settings ****
    But how do i tell the compiler the device is running with pll on at 16Mhz? At this moment my led blinks way to fast when toggling at 1Hz....

    Thanks in advance.

    You might check your Declare XTAL.
    If you are using a PLL you'll have to make sure the XTAL corresponds with the actual oscillator frequency.
    E.g. you have a crystal of 5 MHz and a PLL of 4, the actual oscillator frequency would be 20, so Declare XTAL = 20.
