Hi,
I'm playing with the DSP and I encounter a problem with the div I don't understand.
I want to divide B by Y1 :
B: B2: 00 B1: 01e000 B0: 000000
Y1: 000100
My code is :
andi #$fe,ccr
rep #24
div y1,b
move b0,b
I would expect the result to be $1e0, but I get :
B: B2: 00 B1: 03bf00 B0: 7ffe20
Does someone sees what is wrong in my div ?
Regards
Laurent
