 * Function:        void OSCREFConfig(unsigned long int source, OSCREFConfigFlags config, unsigned long int div);
 *
 * Description:     Sets Reference Oscillator options and ref clock source
 *
 * PreCondition:    Interrupts must be disabled
 *
 * Inputs:          Clock source, PLL multiplier, PLL postscaler, FRC divisor
 *
 * Output:          None
 *
 * Example:         OSCREFConfig(OSC_REFOCON_PBCLK, OSC_REFOCON_OE, 2);
 *
 * Note:            None
