The IOWR instruction is used to set the addresses of the words in the CPU
Unit with which to exchange position data. If the operation is completed nor-
mally, the Equals Flag (one of the Conditions Flags) will turn ON and the set-
tings will be enabled. Under the following conditions the operation will not be
completed normally.
• If an intelligent transfer requested immediately before has not been com-
pleted.
• If the Teaching Box is in Enabled Mode or Occupy Mode.
• If a number other than 2 is specified as the number of words to be trans-
ferred.
• If the data is out of range.
The other Condition Flags operate the same as for other addresses used for
IORD/IOWR in the MC Unit. (Refer to the Flags on page 210 .)
