1) After switching the CE pin to the high level, hold it at the high level until any
subsequent operation requires switching it to the low level. (Note that switch-
ing the CE pin to the low level sets the WTEN bit to 1.)
*
2) Write 0h for the 12-hour format or 4h for the 24-hour time display system.
*
3) The BSY bit is held at 1 for a maximum duration of 122.1 us.
*
4) Switch the CE pin to the low level to set the WTEN bit to 1.
During write operation to the clock and calendar counters, one 1-second digit
carry causes a 1-second increment while two 1-second digit carries also
cause only a 1-second increment, which, in turn, causes a time delay.
*
5) When needing any higher-order digits than the minute digits, replace second
digits with minute digits. (Reading LSD one of the required digits twice.)
*
6) Select the level mode as an interrupt mode by setting the CT3 bit to 1.
*
7) Write 2h for the 12-hour format or 6h for the 24-hour format.
*
8) Complete read operation within an interrupt cycle after interrupt generation
(e.g. within 1 second).

Read data as described in 11.3-2 or 11.3-3 when it takes (1/1024) sec or more to set the WTEN bit from 0 to 1 (CE=L),
the read operation described in 11.3-1 is prohibited as such a case.
