// Return Value : None

// Parameters

: None

//

// The SMBus peripheral is configured as follows:

// - SMBus enabled

// - Slave mode disabled

// - Timer1 used as clock source. The maximum SCL frequency will be

//

approximately 1/3 the Timer1 overflow rate

// - Setup and hold time extensions enabled

// - Free and SCL low timeout detection enabled

//

void SMBus_Init (void)

{

SMB0CF = 0x5D;

// Use Timer1 overflows as SMBus clock

// source;

// Disable slave mode;

// Enable setup & hold time extensions;

// Enable SMBus Free timeout detect;

// Enable SCL low timeout detect;

SMB0CF |= 0x80;

// Enable SMBus;

}
