DS30412C-page 129 PIC17C4X MULLW Multiply Literal with WREG Syntax: [ label ] MULLW k Operands: 0 ≤ k ≤ 255 Operation: (k x WREG) → PRODH:PRODL Status Affected: None Encoding: 1011 1100 kkkk kkkk Description: An unsigned multiplication is carried out between the contents of WREG and the 8-bit literal 'k'. The 16-bit result is placed in PRODH:PRODL register pair. PRODH contains the high byte. WREG is unchanged. None of the status flags are affected. Note that neither overflow nor carry is possible in this operation. A zero result is possible but not detected. Words: 1 Cycles: 1 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode Read literal 'k' Execute Write registers PRODH: PRODL Example: MULLW 0xC4 Before Instruction WREG = 0xE2 PRODH = ? PRODL = ? After Instruction WREG = 0xC4 PRODH = 0xAD PRODL = 0x08 Note: This instruction is not available in the PIC17C42 device. MULWF Multiply WREG with f Syntax: [ label ] MULWF f Operands: 0 ≤ f ≤ 255 Operation: (WREG x f) → PRODH:PRODL Status Affected: None Encoding: 0011 0100 ffff ffff Description: An unsigned multiplication is carried out between the contents of WREG and the register file location 'f'. The 16-bit result is stored in the PRODH:PRODL register pair. PRODH contains the high byte. Both WREG and 'f' are unchanged. None of the status flags are affected. Note that neither overflow nor carry is possible in this operation. A zero result is possible but not detected. Words: 1 Cycles: 1 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode Read register 'f' Execute Write registers PRODH: PRODL Example: MULWF REG Before Instruction WREG = 0xC4 REG = 0xB5 PRODH = ? PRODL = ? After Instruction WREG = 0xC4 REG = 0xB5 PRODH = 0x8A PRODL = 0x94 Note: This instruction is not available in the PIC17C42 device. |
