MBF200 fingerprint sensor

hey!!i tried initialising the sensor...the interrupt pin goes low when finger is placed and the status of last 2 bits of control c register are reflecte on p0,p1 pins of the sensor...However am not able to read registers in the sensor...plz help!

//---------------------------
// write into mbf register
//---------------------------
void Write_Reg(unsigned char reg,unsigned char data)
{

 	 DDRC = 0xFF;		//portc as output 
 	 
	 //select a particular register
	 
 	 PORTA &= ~(1<<PA0);
	 
	 PORTA |= (1<<PA1);
	 
	 PORTA &= ~(1<<PA2);
	 
	 PORTC = reg;			 
	 
	 //send data to register
	 
	 _delay_us( 45 );;					   //40us delay	 

	 PORTA |= (1<<PA0);
	 
	 PORTC = data;

	 _delay_us( 45 );;					   //40us delay	
}

//---------------------------
// mbf initialization
//---------------------------


void mbf_initial(void)
{
 	 
	 Write_Reg(0x08,0x00);	 	   //reset value of CTRLA reg
	 
	 Write_Reg(0x0F,0x33);		   //set threshold value(houzee) (adjust)
	 
	 Write_Reg(0x09,0x0D);		   //set value of CTRLB register
	 
	 _delay_us( 45 );;					   //40us delay
	 
	 Write_Reg(0x06,0x40);		   //discharge time register value(houzee)
	 
	 Write_Reg(0x07,0x10);		   //discharge current register value(houzee)
	 
	 Write_Reg(0x0C,0x08);		   //gain setting (houzee) (adjust)
	 
	 Write_Reg(0x0E,0x03);		   //clear pending work
	 
	 Write_Reg(0x0D,0x51);		   //Interrupt control register (*)
	 
	 _delay_us( 110 );;			   		   //100us delay
