Effective Addresses Calculation
The effective address is Rn plus a 4-bit
displacement (disp). disp is zero-extended, and
remains the same for a byte operation, is doubled
for a word operation, and is quadrupled for a
longword operation.
The effective address is the GBR value plus an 8-
bit displacement (disp). The value of disp is zero-
extended, and remains the same for a byte
operation, is doubled for a word operation, and is
quadrupled for a longword operation.
The effective address is the GBR value plus the R0
value.
