Description
Data set in INT1 register_1 is considered as frequency duty data. By settin
each bit from bit[4:0] of the register to “1”, the frequency corresponding
each bit is selected in an ANDed form. The SC bits configure a 3-bit SRAM
type register that can be set freely by users. These bits can be read an
written within the operating voltage range (1.3 to 3.0 V). There is no impac
on the duty function

Description
A2WE, A2HE, and A2mE are respectively in the MSB of each byte. By
setting every bit to “1”, the setting of the day of week data, hour data, and
minute data in the corresponding bye becomes valid.

For a 12-hour expression, write 0 and 1 for AM and PM, respectively. For a
24-hour expression, either 0 or 1 can be written. 0 is read when the hour
data is from 00 to 11, and 1 is read when from 12 to 23.
