Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
EQ (A50006): The result is 0.
N (A50008): Shows the status of bit 15 of R+1 after execution.
Example When CIO 000000 is ON in the following example, the logical exclusive NOR is
taken of corresponding bits in CIO 0010 to CIO 0011 and CIO 0020 to CIO 0020
and the results is placed in corresponding bits of D00200 and D00201.

When the execution condition is OFF, COM(138) is not executed. When the ex-
ecution condition is ON, COM(138) turns OFF all ON bits and turns ON all OFF
bits in Wd.
Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
EQ (A50006): The result is 0.
N (A50008): Shows the status of bit 15 of R after execution.
Example When CIO 000000 is ON in the following example, the complement of the status
of each bit in D02000 is taken and written back to D02000, i.e., the status of each
bit is reversed.
