These instructions affect the following Special Memory bits: SM1.0 (zero); SM1.1
(overflow); SM1.2 (negative); SM1.3 (divide-by-zero)
If SM1.3 (divide by zero) is set during a divide operation, then the other math
status bits are left unchanged and the original input operands are not altered.
Otherwise, all supported math status bits contain valid status upon completion of
the math operation.

The Multiply Integer to Double Integer instruction
multiplies two 16-bit integers and produces a 32-bit
MUL
ENO
product.
OUT OUT The Divide Integer to Double Integer instruction
divides two 16-bit integers and produces a 32-bit result
consisting of a 16-bit remainder (most-significant) and a
16-bit quotient (least-significant).
DIV
ENO
In the STL Multiply instruction, the least-significant word
(16 bits) of the 32-bit OUT is used as one of the factors.
OUT OUT
In the STL Divide instruction, the least-significant word
(16 bits) of the 32-bit OUT is used as the dividend.
In LAD and FBD: IN1 IN2 = OUT
