I’ve started to run Toni Wilen’s 'cputester' in vAmiga.
Toni's test CHK.W fails due to a wrong value of the N flag if an exception happens.
CHK.W
Musashi sets the N flag as follows:
FLAG_N = (src < 0)<<7;
The correct logic of CHK <ea>,Dn seems to be:
CHK <ea>,Dn
IF ([Dn] > [ea]) N := 'Negative-bit of Dn' ELSE IF ([Dn] < 0) N := 1
The text was updated successfully, but these errors were encountered:
