Hi all,
       I have used the following code for I2C intializing, the vector
no 9, i dont receive i2c interrupt(IRQ) after setting the start bit.

if I configure the interrupt as FIQ I receive the interrupt.

#define VIC_ENABLE  (1<<5)
#define VIC_BIT(b)   (1<<b)
#define VIC_I2C      9

void  i2c_init(void)
   {
     I2C_I2CONCLR =0xFF ;
    /**I2C GPIO INIT***/
    PCB_PINSEL0 &= ~0x000000F0;
    PCB_PINSEL0 |=  0x00000050;
   
   /*Setting the LPC2104 slave address*/
    I2C_I2ADR = LPC2104_ADDR | 0x01;


    I2C_I2SCLL   = 80;
    I2C_I2SCLH   = 80; 

    /*i2c interrupt flag is cleared and i2c is enabled*/

   I2C_I2CONSET = 0x40;
	 

	    /*enabling i2c interrupt,make I2C interrupt as IRQ*/
    VICIntSelect &= ~VIC_BIT(VIC_I2C);
    VICVectAddr0 =(unsigned int)lpci2c_isr;
	VICVectCntl0 = VIC_ENABLE | VIC_I2C;
	VICIntEnable = VIC_BIT(VIC_I2C);   
   }

thanks
