Effective Addresses Calculation
The effective address is the PC value sign-extended
with an 8-bit displacement (disp), doubled, and
added to the PC value.
The effective address is the PC value sign-extended
with a 12-bit displacement (disp), doubled, and
added to the PC value.
The effective address is the register PC value
plus Rn.
The 8-bit immediate data (imm) for the TST, AND,
OR, and XOR instructions are zero-extended.
The 8-bit immediate data (imm) for the MOV, ADD,
and CMP/EQ instructions are sign-extended.
The 8-bit immediate data (imm) for the TRAPA
instruction is zero-extended and is quadrupled.
