When the execution condition is OFF, MULL(56) is not executed. When the
execution condition is ON, MULL(56) multiplies the eight-digit content of Md
and Md+1 by the content of Mr and Mr+1, and places the result in R to R+3.
R + 3
ER: Md, Md+1,Mr, or Mr+1 is not BCD.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
CY: ON when there is a carry in the result.
EQ: ON when the result is 0.

When the execution condition is OFF, DIVL(57) is not executed. When the
execution condition is ON, DIVL(57) the eight-digit content of Dd and D+1 is
divided by the content of Dr and Dr+1 and the result is placed in R to R+3: the
quotient in R and R+1, the remainder in R+2 and R+3.

ER: Dr and Dr+1 contain 0.
Dd, Dd+1, Dr, or Dr+1 is not BCD.
