Function
Rd ∧ Rs → Rd, Rd ∧ #imm → Rd
Performs a logical AND operation on a general register and another
general register or immediate data.
Rd ∨ Rs → Rd, Rd ∨ #imm → Rd
Performs a logical OR operation on a general register and another
general register or immediate data.
Rd ⊕ Rs → Rd, Rd ⊕ #imm → Rd
Performs a logical exclusive OR operation on a general register and
another general register or immediate data.
¬ (Rd) → (Rd)
Obtains the one’s complement (logical complement) of general
register contents.
2.5.4 Shift Operations
Table 2.7 describes the eight shift instructions. Figure 2.6 shows the object code formats of the
arithmetic, logic, and shift instructions.
