Effective Addresses Calculation
The effective address is the GBR value plus the R0.
The effective address is the PC value plus an 8-bit
displacement (disp). The value of disp is zero-
extended, and is doubled for a word operation, and
quadrupled for a longword operation. For a
longword operation, the lowest two bits of the PC
value are masked.
