Immediate #imm:8 8-bit immediate data imm of TST, AND, OR, or XOR
instruction is zero-extended.
#imm:8 8-bit immediate data imm of MOV, ADD, or CMP/EQ
instruction is sign-extended.
#imm:8 8-bit immediate data imm of TRAPA instruction is
zero-extended and multiplied by 4.
Note: For the addressing modes below that use a displacement (disp), the assembler descriptions
in this manual show the value before scaling (×1, ×2, or ×4) is performed according to the
operand size. This is done to clarify the operation of the LSI. Refer to the relevant
assembler notation rules for the actual assembler descriptions.
@ (disp:4, Rn) ; Register indirect with displacement
@ (disp:8, GBR) ; GBR indirect with displaceme nt
@ (disp:8, PC) ; PC-relative with displacement
disp:8, disp:12 ; PC-relative
