Comparison Instructions Section 5-18
Flags ER: Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON if Cp1+1, Cp1 equals Cp2+1, Cp2.
LE: ON if Cp1+1, Cp1 is less than Cp2+1, Cp2.
GR: ON if Cp1+1, Cp1 is greater than Cp2+1, Cp2.
Example In the following example, the content of 103, 102 is less than that of DM 0021,
DM 0020, so 10002 is turned ON and the other bits, 10000 and 10001, are
turned OFF.
5-18-8 AREA RANGE COMPARE – ZCP(––)
Limitations This instruction is available in the CQM1-CPU4@-E/-EV1 only.
LL must be less than or equal to UL.
Description When the execution condition is OFF, ZCP(––) is not executed. When the exe-
cution condition is ON, ZCP(––) compares CD to the range defined by lower
