(Default)
(0)
The binary encoded settings in the seven bits from F6 to F0 are used to set the precision of the clock generated
from the 32768-Hz internal oscillator up to
±189 × 106 in the forward (ahead) or reverse (behind) direction, in
units of
± 3.05 × 106. (Only the clock precision can be adjusted. The 32.768-kHz output from the FOUT pin is
not affected.)
When not using this function, be sure to set "0" for bits F6 to F0.
For details, see "8.3. Clock Precision Adjustment Function".

The Alarm W function is used, along with the WALE and WAFG bits, to set alarms for specified day, hour, and
minute values.
When the Alarm_W setting matches the current time, /INTB pin is set to "L" and the WALE bit is set to "1".
Note: If the current date/time is used as the Alarm_W setting, the alarm will not occur until the counter counts up
to the current date/time (i.e., an alarm will occur next time, not immediately).
During 24-hour clock operation, the "Alarm_W ; Hours" register's bit 5 (WH20, WP, /A) functions as WH20
(two-digit hour display), and during 12-hour clock operation it functions as an AM/PM indicator.
When the Alarm_W function's day values (WW6 to WW0) are all "0" Alarm W does not occur.
For details, see "8.5. Alarm W Function".

The Alarm D function is used, along with the DALE and DAFG bits, to set alarms for specified hour and minute
values.
When the Alarm_D setting matches the current time, /INTA pin is set to "L" and the DALE bit is set to "1".
Note: If the current time is used as the Alarm_D setting, the alarm will not occur until the counter counts up to the
current time (i.e., an alarm will occur next time, not immediately).
During 24-hour clock operation, the "Alarm_D ; Hours" register's bit 5 (DH20, DP, /A) functions as DH20 (two-digit
hour display), and during 12-hour clock operation it functions as an AM/PM indicator.
For details, see "8.6. Alarm D Function".
