ARM INSTRUCTION SET
S3C3410X RISC MICROPROCESSOR
NOTE
Some instruction codes are not defined but do not cause the Undefined instruction trap to be taken, for
instance a Multiply instruction with bit 6 changed to a 1. These instructions should not be used, as their
action may change in future ARM implementations.

Action
Rd: = Rn + Op2 + Carry
Rd: = Rn + Op2
Rd: = Rn AND Op2
R15: = address
Rd: = Rn AND NOT Op2
R14: = R15, R15: = address
R15: = Rn, T bit: = Rn[0]
(Coprocessor-specific)
CPSR flags: = Rn + Op2
CPSR flags: = Rn – Op2
Rd: = (Rn AND NOT Op2)
OR (Op2 AND NOT Rn)
Coprocessor load
Stack manipulation (Pop)
Rd: = (address)
cRn: = rRn {<op>cRm}
Rd: = (Rm × Rs) + Rn
Rd: = Op2
