Repeat Operation in the MUL Instruction
Since the MUL (multiplication) instruction uses two destination devices, the result is stored to destination devices as described
below. Source devices S1 and S2 and destination device D1 can be designated to repeat individually or in combination. When
destination device D1 is not assigned to repeat, the final result is set to destination device D1 and D1+1. When repeat is
designated, consecutive devices as many as the repeat cycles starting with the designated device are used.
Since the repeat operation works similarly on word and integer data, the following examples are described using word data.
Repeat One Source Device
When only S1 (source) is assigned to repeat, the final result is set to destination device D1·D1+1.
• Data Type: Word and Integer
• Data Type: Double Word, Long, and Float
Repeat Destination Device Only
When only D1 (destination) is assigned to repeat, the same result is set to 3 devices starting with D1·D1+1.
• Data Type: Word and Integer
• Data Type: Double Word, Long, and Float
Repeat Two Source Devices
When S1 and S2 (source) are assigned to repeat, the final result is set to destination device D1·D1+1.
• Data Type: Word and Integer
• Data Type: Double Word, Long, and Float
