Burst programming from a FLASH Block to another one. - HCS08GT60.

Hi all,
 
 In order to defrag a FLASH part used to store non volatile data, I try to programm another FLASH zone in burst mode.
 
 I do this on a HCS08GT60.
 
The data I need to write are in another FLASH location. So during the Flash programming algorithm, I do a read access in FLASH (more precisely just before the "WRITE TO FLASH TO BUFFER ADDRESS AND DATA" ) to get my data.
 
 The result is that the first data is well written when I look at the FLASH with the debugger but all the following data are not correctly written (they are all to 0x04 when I look to the FLASH with the debugger ??????).
 
No FACCER is detected.
 
I suppose the read access in FLASH during the burst programming sequence is forbidden and can explain this comportment.
 
Anybody can help me ?
 
Added p/n to subject.
