The rightmost three digits of Di must each be between 0 and 3.
DM 6144 to DM 6655 cannot be used for Di or D.
When the execution condition is OFF, MOVD(83) is not executed. When the
execution condition is ON, MOVD(83) copies the content of the specified
digit(s) in S to the specified digit(s) in D. Up to four digits can be transferred at
one time. The first digit to be copied, the number of digits to be copied, and
the first digit to receive the copy are designated in Di as shown below. Digits
from S will be copied to consecutive digits in D starting from the designated
first digit and continued for the designated number of digits. If the last digit is
reached in either S or D, further digits are used starting back at digit 0.
Digit number: 3 2 1 0
