các bác xem giùm nó báo lỗi gì???

#include <p30F2020.h>

_FOSC(CSW_FSCM_OFF & FRC_PLL4);
_FWDT(WDT_OFF);
_FBORPOR(PBOR_OFF & MCLR_EN);
_FGS(CODE_PROT_OFF);

//------------------------------------------------------------------------------

#define Fcy 8000000 //Tan so thuc thi lenh
#define Fpwm 100000 //Tan so PWM = 100 kHz

//Chuong trinh con khoi tao module PWM
void Init_MCPWM(void)
{
PTPER = Fcy/Fpwm - 1; //Dat thanh ghi chu ky voi tan so PWM = 100 kHz
SEVTCMP = PTPER;
PWMCON1 = 0x0111; //Chi dung cac chan PxL, mot cach doc lap
DTCON = 0x0032;
OVDCON = 0xFF00; //Khong dung overdrive
PDC1 = 0x0064; //Khoi tao PWM1, 2 la 25%
PWMCON2 = 0x0F00; //Postscale = 1:16
PTCON = 0x8000; //Kich hoat module PWM
}

int main(void)
{
Init_MCPWM();
}

lỗi báo là:

tôi đang dùng dspic30f2020 viết chương trình dùng clock nội thì nó chạy được còn dùng thạch anh không hiểu sao nó không hoạt động được?
