Description When
the execution condition is OFF
, ZCP(88) is
not executed. When the exe
-
cution
condition is ON, ZCP(88) compares CD
to the range defined by lower limit
LL
and upper limit UL and outputs the result to the GR, EQ, and LE flags in the
SR area. The resulting flag status is shown in the following table.
