Syntax

op{S}{cond} {Rd,} Rn, Operand2

where:

op

is one of:

AND logical AND.

ORR logical OR, or bit set.

EOR logical Exclusive OR.

BIC logical AND NOT, or bit clear.

ORN logical OR NOT.

S

is an optional suffix. If S is specified, the condition code flags are updated on the result of the 
operation, see 

cond

is an optional condition code, see 

.

Rd

is the destination register.

Rn

is the register holding the first operand.

Operand2

is a flexible second operand. See 

 for details of the

options

Operation

The AND, EOR, and ORR instructions perform bitwise AND, Exclusive OR, and OR operations on the values in Rn
and Operand2.

The BIC instruction performs an AND operation on the bits in Rn with the complements of the corresponding bits in
the value of Operand2.

The ORN instruction performs an OR operation on the bits in Rn with the complements of the corresponding bits in
the value of Operand2.

Restrictions

Do not use SP and do not use PC.

Condition Flags

If 

S

 is specified, these instructions:



Update the N and Z flags according to the result



Can update the C flag during the calculation of Operand2, see 



Do not affect the V flag.
