Operation End Time
(Not supported by CJ1@-
CPU@@ CPU Units.)
A518 to
A520
The time that operation stopped as a result of changing the
operating mode to PROGRAM mode is stored here in BCD.
A51800 to A51807: Seconds (00 to 59)
A51808 to A51815: Minutes (00 to 59)

Note: If an error occurs in operation, the time of the error will
be stored. If the operating mode is then changed to PRO-
GRAM mode, the time that PROGRAM mode was entered
will be stored.
