When the Shift Enable Bit (bit 14 of C) is ON, all of the words with non-zero
content within the range of words between St and E will be shifted one word in
the direction determined by the Shift Direction Bit (bit 13 of C) whenever the
word in the shift direction contains all zeros. If ASFT(017) is repeated suffi-
cient times, all all-zero words will be replaced by non-zero words. This will
result in all the data between St and E being divided into zero and non-zero
data.
