XC8 de bu işlemci için konfigürasyon ayarlarını yapamadım.İşlemcinin kendi içindeki Internal 32MHz oscillator'Ü kullanmak istiyorum.Basit bir örnek örnek çalıştıramadım.

Tamam hallettim. :)
main.h da pragmalardan sonra frekansı unuttuk.
#define _XTAL_FREQ 32000000
main.c de OSCCON registerini şöyle ayarlıyoruz.(Internal kullanmak için)
OSCCON=0b01110010;
Datasheet de OSCCON kısmına bakabilirsiniz. http://ww1.microchip.com/downloads/en/DeviceDoc/41391D.pdf (http://ww1.microchip.com/downloads/en/DeviceDoc/41391D.pdf)
