Hello
I am in the process od sending datas to a serial PLL (MB88006)
the register A should have a value between 0 and 63 ..
as soon as this variable is out this range I must Increment or decrement another register (N)
question :
assuming variable A value is 0
if I have the order
A= A-1
and after
IF A < 0 then A = 63 : N = N - 1
(for me A as the value -1 (minus 1) and the IF is working !)

it seems NOT ...

what is wrong on my side ?
thanks
Francois
