2.6.6.1.4 Condition Flags

If S is specified, the MUL instruction:

• updates the N and Z flags according to the result
• does not affect the C and V flags.

Examples

MUL R10, R2, R5    ; Multiply, R10 = R2 x R5
MLA R10, R2, R1, R5          ; Multiply with accumulate, R10 = (R2 x R1) + R5
MULS R0, R2, R2              ; Multiply with flag update, R0 = R2 x R2
MULLT R2, R3, R2             ; Conditionally multiply, R2 = R3 x R2
MLS R4, R5, R6, R7           ; Multiply with subtract, R4 = R7 - (R5 x R6).
