DT90058 -
Note) After discharging the battery (including when the power is turned on for the first time), the values of
DT90053 to DT90058 change at random. Once the time and date have been set, these values will
function normally.

Descriptions
The Real-Time Clock(Clock/Calendar) is
adjusted as follows.
When setting the Real-Time Clock
(Clock/Calendar) by program
By setting the highest bit of DT90058 to 1, the
time becomes 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 5
X0 turns on.
If you changed the values of DT90054 to
DT90057 with the data monitor functions of
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.
