Description
Multiplies the 32-bit data or 32-bit equivalent constant specified by S1 and the one specified by S2.
The multiplied result is stored in D+3, D+2, D+1 and D.
Multiplicand data Result
(S1+1, S1) (D+3, D+2, D+1, D)× (S2+1, S2)
Multiplier data
The multiplied result is stored in the 64-bit area.
When processing 32-bit data, the higher 16-bit areas (S1+1, S2+1) are automatically determined once the
lower 16-bit areas (S1, S2) are specified.
The areas (D+3, D+2, D+1) other than the lowest 16-bit area (D) are automatically determined once the
lowest 16-bit area is specified.
Flag conditions
・Error flag (R9007): Turns on and stays on when the area specified using the index modifier
exceeds the limit.
・Error flag (R9008): Turns on for an instant when the area specified using the index modifier
exceeds the limit.
・= flag (R900B): Turns on for an instant when the calculated result is recognized as “0”.
