Effective Address Calculation
The effective address is the sum of PC value and
the value that is obtained by doubling the sign-
extended 8-bit displacement (disp).
The effective address is the sum of PC value and
the value that is obtained by doubling the sign-
extended 12-bit displacement (disp).
The effective address is the sum of the register PC
and Rn.
The 8-bit immediate data (imm) for the TST, AND,
OR, and XOR instructions is zero-extended.
The 8-bit immediate data (imm) for the MOV, ADD,
and CMP/EQ instructions is sign-extended.
The 8-bit immediate data (imm) for the TRAPA
instruction is zero-extended and then quadrupled.
