我用的gz16的芯片，设置用中断来接收PC机发送的数据，可以好象没有产生中断，不知道是为什么，下面是我得程序。

#include <hidef.h> /* for EnableInterrupts macro */
#include "derivative.h" /* include peripheral declarations */

unsigned char temp=0;
unsigned char rxdata=0;
void MCU_init(void); /* Device initialization function declaration */

void main(void) {

  unsigned char temp,rxdata;
  temp=0;
  rxdata=0;
  PTD=0;
  DDRD=0xff;//output
  /* include your code here */
  CONFIG1=0x39;
  CONFIG2=0x10;

  SCBR=0x30;//baud rate 9600
 SCC1=0x40;//enable SCI,no parity test,8bit data

  SCC2=0x2C;//enable transmitter and receiver
  SCC3=0x00;
  SCC2_SCTIE=0;
  EnableInterrupts; /* enable interrupts */
  /* include your code here */

  for(;;) {
    __RESET_WATCHDOG(); /* feeds the dog */
  } /* loop forever */
  /* please make sure that you never leave this function */
}

interrupt void SCRF(void)
{
 temp=SCS1;
 rxdata=SCDR;
  if(rxdata==0x55)  PTD_PTD0=1;
  else PTD_PTD2=1;
                                                   
  // SCC2_SCTIE=1;
 }
