Hi all,
Am using C8051F340 controller .Also attached schematics file. In that port-0 am using SPI . port1 SDA& SCL lines. In that initializing XBR and Pskip. SPI working fine,but SMBus not working. can anyone tell me suggesstion for this init is correct or wrong.

Code: 
	P0MDOUT |= 0x1D;                   
   	P0 = 0xFF;
   	P1MDOUT = 0x04;              
   	P1 = 0xFF;

	XBR0     = 0x0F;               
   	XBR1     = 0x40;                    
   	XBR2 	= 0X01;	
					
   	P0SKIP = 0XC0; 
   	P1SKIP = 0XF0;
