Isd 33120 Chipcorder

I am trying and trying to write Pic Basic code for my ISD33120 to RECORD and PLAY voice messages, but nothing happened. I just have no idea how to do this

ISD33120 require SPI comunication: MISO,MOSI,CLK AND SS to interface with PIC (in my case 16F877), and there is an OPCODE <5 bits> and ADDRESS <11 bits> necessary for manage 33120 so I decided to go by SHIFTOUT command, to send that WORD-sized data to 33120 chipcorder by MOSI pin.
The first 3 pins on PORTA I used to command what 33120 to do (REC/PLAY/STOP) by 3 buttons.

I`m using a little electrodynamic microphone connected to ANA IN+ pin, ANA IN- pin is grounded, AUD OUT is connected to audio power amplifier.

I will send my code if necessary

THANX A LOT
