Comparison Instructions Section 5-19
Precautions Placing other instructions between CPS(––) and the operation which
accesses the EQ, LE, and GR flags may change the status of these flags. Be
sure to access them before the desired status is changed.
Flags ER: Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON if Cp1 equals Cp2.
LE: ON if Cp1 is less than Cp2.
GR: ON if Cp1 is greater than Cp2.
Example In the following example, the content of 102 is greater than that of DM 0020,
so 10000 is turned ON and the other bits, 10001 and 10002, are turned OFF.
