MC13192 and busy channel

Hi evryone,
i'm using an MC13192 for ZigBee application and i find out some problems when more of one divice is in trasmission mode. There are collision and nothing is received from the receiver device.
Then i try to find out in wich way i could test the channel before a transmission to check if it is busy or not.

I think the register 0x24 do the job through CCA bit.

In code worrior i use this code tring to read the state of CCA bit but without success: register 24 is always 0x0000.

Here it is the code:

UINT16 reg24;
SPIDrvWrite(0x06,0x0411); //I set the CCA mode
SPIDrvWrite(0x04,0x058D); //I set a very low treeshold: 0x05


for( ;; ){
reg24 = SPIDrvRead( 0x24 ); //I read to infinite the register while
} //another device is transmitting to infinite
//on the same channel

Is this the right way to testing if a channel is busy?
Can anybody help me?
