11.13.1.6
11.13.1.7
The example below shows two instructions that add a 64-bit integer contained in R2 and R3 to another 64-bit integer con-
tained in R0 and R1, and place the result in R4 and R5.
11.13.1.8
Multiword values do not have to use consecutive registers. The example below shows instructions that subtract a 96-bit
integer contained in R9, R1, and R11 from another contained in R6, R2, and R8. The example stores the result in R6, R9,
and R2.

details of the options.
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.
