Instruction Format:
Conditional ALU/MAC Operation, Instruction Type 9:
23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
0 0 1 0 0 Z AMF Yop Xop 0 0 0 0 COND
AMF specifies the ALU or MAC operation. In this case,
AMF = 11100 for AND operation.
AMF = 11101 for OR operation.
AMF = 11110 for XOR operation.
Z: Destination register Yop: Y operand
Xop: X operand COND: condition
(xop
AND/OR/XOR constant)
Conditional ALU/MAC operation, Instruction Type 9:
(ADSP-217x, ADSP-218x, ADSP-21msp58/59 only)
23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
0 0 1 0 0 Z AMF YY Xop CC BO COND
AMF specifies the ALU or MAC operation, in this case:
AMF = 11100 for AND operation.
AMF = 11101 for OR operation.
AMF = 11110 for XOR operation.
Z: Destination register COND: condition
Xop: X operand
BO, CC, and YY specify the constant (see Appendix A, Instruction Coding).
