TSK3000A - Bitwise Logical Instructions
Logical instructions perform bitwise operations and store the resulting values in registers. The instruction format can be R-type or I-type. With R-type instructions, the two operands and the result are register values. With I-type instructions, one of the operands is a 16-bit immediate value, zero extended to 32 bits.
Table 1. Bitwise Logical Instructions.| Mnemonic | Instruction | Description |
|---|---|---|
AND rC, rA, rB | Bitwise Logical AND | Bitwise logically ANDs the contents of GPRs rA and rB and puts the result in GPR rC |
ANDI rB, rA, IMM16 | Bitwise Logical AND Immediate | Zero-extends the 16-bit immediate value, IMM16, bitwise logically ANDs it with the contents of GPR rA and puts the result in GPR rB |
NOR rC, rA, rB | Bitwise Logical NOR | Bitwise logically NORs the contents of GPR rA with the contents of GPR rB, and loads the result in GPR rC |
OR rC, rA, rB | Bitwise Logical OR | Bitwise logically ORs the contents of GPR rA with the contents of GPR rB, and loads the result in GPR rC |
ORI rB, rA, IMM16 | Bitwise Logical OR Immediate | Zero-extends the 16-bit immediate value, IMM16, bitwise logically ORs the result with the contents of GPR rA, and loads the result in GPR rB |
XOR rC, rA, rB | Bitwise Logical Exclusive OR | Bitwise logically exclusive-ORs the contents of GPR rA with the contents of GPR rB and loads the result in GPR rC |
XORI rB, rA, IMM16 | Bitwise Logical Exclusive OR Immediate | Zero-extends the 16-bit immediate value, IMM16, bitwise logically exclusive-ORs it with the contents of GPR rA, then loads the result in GPR rB |
