3.5.1 ADD, ADC, SUB, SBC, and RSB
Add, Add with carry, Subtract, Subtract with carry, and Reverse Subtract.
3.5.1.1 Syntax
op{S}{cond} {Rd,} Rn, Operand2
op{cond} {Rd,} Rn, #imm12
; ADD and SUB only
where:
op
is one of:
ADD
Add.
ADC
Add with Carry.
SUB
Subtract.
SBC
Subtract with Carry.
RSB
Reverse Subtract.
S
is an optional suffix. If S is specified, the condition code flags are updated on the result of
the operation, see Section 3.3.7 (p. 43) .
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
Rd
is the destination register. If Rd is omitted, the destination register is Rn.
Rn
is the register holding the first operand.
Operand2
is a flexible second operand. See Section 3.3.3 (p. 38) for details of the options.
imm12
is any value in the range 0-4095.
3.5.1.2 Operation
The ADD instruction adds the value of Operand2 or imm12 to the value in Rn.
The ADC instruction adds the values in Rn and Operand2, together with the carry flag.
The SUB instruction subtracts the value of Operand2 or imm12 from the value in Rn.
