Usually, 8-, 16-, or 32-bit immediate value, displacement, and absolute are connected after the operation code. In
the case of the above instruction formats (S2, S4, S6, D2, D3, and D5), two or more of immediate value, displace-
ment, and absolute are connected to the operation code. As a whole, these values express a 16-bit immediate value
(imm16), 24-bit immediate value (imm24), 32-bit immediate value (imm32), 40-bit immediate value (imm40),
and 48-bit immediate value (imm48). According to this expression method, the following instructions connect 16-
, 32-, 40-, and 48-bit immediate values.
imm16: RET regs,imm8
RETF regs,imm8
BTST imm8,(d8,An)
BSET imm8,(d8,An)
BCLR imm8,(d8,An)
imm24: BTST imm8,(abs16)
BSET imm8,(abs16)
BCLR imm8,(abs16)
imm32: CALL (d16,PC),regs,imm8
imm40: BTST imm8,(abs32)
BSET imm8,(abs32)
BCLR imm8,(abs32)
imm48: CALL (d32,PC),regs,imm8
