Effective Address Calculation Method
Effective address is PC + 4 with 12-bit
displacement disp added after being sign-extended
and
multiplied by 2.
Effective address is sum of PC + 4 and Rn.
8-bit immediate data imm of TST, AND, OR, or
XOR instruction is zero-extended.
8-bit immediate data imm of MOV, ADD, or
CMP/EQ instruction is sign-extended.
8-bit immediate data imm of TRAPA instruction is
zero-extended and multiplied by 4.
