Flags ER: The comparison block (i.e., CB through CB+31) exceeds the data
area.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
Example The following example shows the comparisons made and the results provided
for BCMP(68). Here, the comparison is made during each cycle when IR
00000 is ON.
