has a word operand form and a long operand form.
In the word form, the multiplier and multiplicand are both word operands, and the result
is a long-word operand. A register operand is the low-order word; the upper word of the
register is ignored. All 32 bits of the product are saved in the destination data register.
In the long form, the multiplier and multiplicand are both long- word operands, and the
result is either a long word or a quad word. The long-word result is the low-order 32 bits
of the quad- word result; the high-order 32 bits of the product are discarded.
X — Not affected.
N — Set if the result is negative; cleared otherwise.
Z — Set if the result is zero; cleared otherwise.
V — Set if overflow; cleared otherwise.
C — Always cleared.

Overflow (V = 1) can occur only when multiplying 32-bit
operands to yield a 32-bit result. Overflow occurs if any of the
high-order 32 bits of the quad-word product are not equal to
zero.
