Can someone explain for phase locked loop (for synchronization purpose) for 440 Hz-500 Hz Sine Wave Tone for sound application using PIC Microcontroller

Can some one explain circuit along with Pseudo code for PIC controller say PIC16F887
 

Research about "all digital PLL".

Circuit is simple, connect input signal to ADC input. Other option to convert sine to square wave and process with digital input.

How about the negative half cycle of SINE wave as PIC reads only +ve half
