DT90058 Clock/calendar
time setting and
30 seconds
correction
register
The clock/calendar is adjusted as follows.
When setting the clock/calendar by program
By setting the the highest bit of DT90058 to 1, the time be-
comes that written to DT90054 to DT90057 by F0 (MV)
instruction. After the time is set, DT90058 is cleared to 0.
(Cannot be performed with any instruction other than
F0 (MV) instruction.)
Example:
Set the time to 12:00:00 on the 5th day when the X0 turns on.
If you changed the values of DT90054 to DT90057 with the
programming tool software, the time will be set when the
new values are written. Therefore, it is unnecessary to write
to DT90058.
When the correcting times less than 30 seconds
By setting the lowest bit of DT90058 to 1, the value will be
moved up or down and become exactly 0 seconds. After the
correction is completed, DT90058 is cleared to 0.
Example:
Correct to 0 seconds with X0 turns on
At the time of correction, if between 0 and 29 seconds, it will
be moved down, and if the between 30 and 59 seconds, it
will be moved up. In the example above, if the time was 5
minutes 29 seconds, it will become 5 minutes 0 second; and,
if the time was 5 minutes 35 seconds, it will become 6
minutes 0 second.
