DM 6144 to DM 6655 cannot be used for R.
MLB(52) cannot be used to multiply signed binary data.
When the execution condition is OFF, MLB(52) is not executed. When the
execution condition is ON, MLB(52) multiplies the content of Md by the contents
of Mr, places the rightmost four digits of the result in R, and places the leftmost
four digits in R+1.

DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ : ON when the result is 0.
7-22-4 BINARY DIVIDE – DVB(53)
Dd : Dividend word (binary)

DVB(53) cannot be used to divide signed binary data.
When the execution condition is OFF, DVB(53) is not executed. When the
execution condition is ON, DVB(53) divides the content of Dd by the content of
Dr and the result is placed in R and R+1: the quotient in R, the remainder in R+1.
