calculation errors ?

Hello Christian,

I experience same strange calculation errors :

For exemple this 32 bit integer division fails, 0x1DDDC/0xE000 give me
0xE instead of 0x02

asm
{
move.l 	0x1DDDC,B
move.w 	0xE000,X0 
ASL 	B          ; Shift of dividend required for integer division
BFCLR 	#$0001,SR  ; Clear carry bit: required for 1st DIV instruction
REP 	16			
DIV 	X0,B       ; Form positive quotient in B0
MOVE.W 	B0,Y1      ; Save quotient in Y1	
}
 
I am working with the latest version of CodeWarrior for DSP56800 and
my hardware is a 56F8355.

Maybe my code is wrong anyone can explain me where is the problem ?

thanks

Alexandre
