LCD_A controller on MSP430F4616 , segments 0- 3 problem

Hi

I am using MSP430F4616 processor , I use the built in LCD_A controller of this  MCU . We have 32 segments  LCD connected to LCD_A controller.

The LCD_A configured  with flowing settings

  // ********LCDACTL register

    //LCDFREQx  - 001 ACLK Divide by 64

    //LCDMXx    - 11 4-mux

    //LCDSON    - 0  All LCD segments are off

    //LCDON     - 1 LCD ,module is on

    LCDACTL = LCDON | LCD4MUX | LCDFREQ_64;

    //**********LCDAPCTL0, LCD_A Port Control Register 0

    //LCDS28 - off

    //LCDS24

    //LCDS20    all on

    //LCDS16

    //LCDS12

    //LCDS8

    //LCDS4

    //LCDS0

    LCDAPCTL0 = LCDS0 | LCDS4 | LCDS8 | LCDS12 | LCDS16 | LCDS20 | LCDS24 | LCDS28;

    //************** LCDAPCTL1, LCD_A Port Control Register 1

    //LCDS36  - off

    //LCDS32  - on

    LCDAPCTL1 = LCDS32;

    //**************LCDAVCTL0, LCD_A Voltage Control Register 0

    //R03EXT - 1 V5 is sourced from the R03 pin

    //REXT   - 1 V2 - V4 are sourced externally and the internal bias generator is switched off

    //VLCDEXT - 0 VLCD is generated internally

    //LCDCPEN - 0 Charge pump disabled.

    //VLCDREFx - Charge pump reference select default 0

    //LCD2B    - Bias select, 0 - 1/3 bias

    LCDAVCTL0 = LCDR03EXT |LCDREXT  ;

    //*****************LCDAVCTL1, LCD_A Voltage Control Register 1

    //VLCDx Bits - Charge pump voltage select - 0 disabled

    LCDAVCTL1 = 0;

I have problems with  segment 0  - to segment 3  , I just see nothing when I write to those segments , the another segments (4- 31) working ok.

As I understand , the segment 0 -3 in 4616 its multifunctional pins , which can be GPIO/Analog input/LCD pins.  

I configure those pins to be peripherals , via appropriate bits in Port selection register.

But how can I , chose between Analog input and LCD functionality ?  

What can be another problem with those segments ?

Thanks a lot

I urgently need the solution for this problem ,please help !!!!
