To make things simple, you'll need to use SHIFTIN/SHIFTOUT in PBP. so it doesn't really matter the PIC I/O you use.

A while back i used a PIC16F628, Bellow is the hardware assignement i used.

    ' I/O Definition
    ' ===============
    '
    TRISA = %00110000    ' PORTA Output on :
                         '         PORTA<3:0> : LCD data 
                         '         PORTA<7:6> : LCD RS & E bit
                         '
                         ' PORTA Input on :
                         '         PORTA.4 : "ALT PLAY" Button
                         '         PORTA.5 : "PLAY" button    
                         '
    TRISB = %11110001    ' PORTB Output on : 
                         '         PORTB.1 : ISD4002 SS pin 
                         '         PORTB.2 : ISD4002 SCLK pin 
                         '         PORTB.3 : ISD4002 MOSI pin
                         '
                         ' PORTB Input on :
                         '         PORTB.0 : ISD4002 INT pin
                         '         PORTB.4 : ISD4002 MISO pin
                         '         PORTB.5 : ISD4002 RAC pin
                         '         PORTB.6 : "SETUP" button
                         '         PORTB.7 : "RECORD" button

Later to write to the ISD chip, i used

    ss = 0
    shiftout MOSI,SCLK,LSBFIRST,[ISDword\16]
    ss = 1

to read from

        ss=0
        shiftin miso,sclk,lsbpre,[isdpointer\16]
        ss=1
