Note :The relations between o8 field of TYPE-B and u4 field of TYPE-C in the instruction format and assembler
description from disp8 to disp10 are as follows:
disp8 → o8 = disp8:Each disp is a code extension.
disp9 → o8 = disp9>>1:Each disp is a code extension.
disp10 → o8 = disp10>>2:Each disp is a code extension.
udisp6 → u4 = udisp6>>2:udisp4 is a 0 extension.
