// MAIN Routine

//-----------------------------------------------------------------------------

//

// Main routine performs all configuration tasks, then loops forever waiting

// for the 'next' button on the board to be pressed. When pressed, the Si570

// will then output the next frequency.

// Temporary counter variable used in

// for loops

// WDTE = 0 (disable watchdog timer)

OSCICN |= 0x03;

// Configure internal oscillator for

// its maximum frequency (24.5 Mhz)

// If slave is holding SDA low because of an improper SMBus reset or error

while(!SDA)

{

// Provide clock pulses to allow the slave to advance out

// of its current state. This will allow it to release SDA.

// Enable Crossbar

SCL = 0;

// Drive the clock low

// Hold the clock low

// Release the clock

while(!SCL);

// Wait for open-drain

// clock output to rise

// Hold the clock high

// Disable Crossbar

}

// Initialize Crossbar and GPIO

// Timer 1 is sysclk

// Timer 2 is sysclk/12 (see TMR2CN)

Timer1_Init ();

// Configure Timer1 for use as SMBus

// clock source

// Configure Timer2 for use with SMBus

// low timeout detect

SMBus_Init ();

// Configure and enable SMBus

Int0_Init ();

// Configure INT0

|= 0x01;

// Enable SMBus interrupt
