Immediate
in this manual indicates the value before it is scaled (x 1, x 2, or x 4) according to the
operand size to clarify the LSI operation. For details on actual assembler description, refer
to the description rules in each assembler.
@ (disp:4, Rn) ; Register indirect with displacement
@ (disp:8, GBR)

Effective Address Calculation Method
Effective address is register PC with 12-bit
displacement disp added after being sign-
extended and multiplied by 2.
Effective address is sum of register PC and Rn
contents.
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.
