Table 6-4. Instruction Notation Conventions

Notation	Description		Actual Operand Range
cc	Condition code	See list of condition codes in Table 6-6.
r	Working register only	Rn (n = 0–15)
rb	Bit (b) of working register	Rn.b	(n = 0–15, b = 0–7)
r0	Bit 0 (LSB) of working register	Rn (n = 0–15)
rr	Working register pair	RRp	(p = 0, 2, 4, ..., 14)
R	Register or working register	reg or Rn (reg = 0–255, n = 0–15)
Rb	Bit "b" of register or working register	reg.b	(reg = 0–255, b = 0–7)
RR	Register pair or working register pair	reg or RRp (reg = 0–254, even number only,
		where p = 0, 2, ..., 14)
IA	Indirect addressing mode	addr	(addr = 0–254, even number only)
Ir	Indirect working register only	@Rn	(n = 0–15)
IR	Indirect register or indirect working register	@Rn or @reg (reg = 0–255, n = 0–15)
Irr	Indirect working register pair only	@RRp (p = 0, 2, ..., 14)
IRR	Indirect register pair or indirect working	@RRp or @reg (reg = 0–254, even only,
	register pair	where p = 0, 2, ..., 14)
X	Indexed addressing mode	#reg[Rn] (reg = 0–255, n = 0–15)
XS	Indexed (short offset) addressing mode	#addr[RRp] (addr = range –128 to +127,
		where p = 0, 2, ..., 14)
XL	Indexed (long offset) addressing mode	#addr [RRp] (addr = range 0–65535, where
		p = 2, ..., 14)
DA	Direct addressing mode	addr	(addr = range 0–65535)
RA	Relative addressing mode	addr	(addr = a number from +127 to –128 that is an
		offset relative to the address of the next instruction)
IM	Immediate addressing mode	#data	(data = 0–255)
IML	Immediate (long) addressing mode	#data	(data = 0–65535)
