Note
During the initial power-on (from 0 V) and if the value of the VLF bit is "1" when the VLF bit is read, be sure to
initialize all registers before using them.
When doing this, be careful to avoid setting incorrect data as the date or time, as timed operations cannot be
guaranteed if incorrect date or time data has been set.
1.
During the initial power-on (from 0 V), the power-on reset function sets "1" to the VLF bit.
Since the value of other registers is undefined at this time, be sure to reset all registers before using them.
2.
The TEST1, TEST2, TEST3 bits are Epson Toyocom test bits.
Be sure to write "0" by initializing before using the clock module. Afterward, be sure to set "0" when writing.
The four TEST* bits are undefined when read. Those bits should be masked after being read.
3.
The ' ' mark indicates a write-prohibited bit, which returns a "0" when read.
4.
The '
' mark indicates a read/write-accessible RAM bit for any data.
5.
The RSV bit are Epson Toyocom test bits.
Be sure to write "0" by initializing before using the clock module. Afterward, be sure to set "0" when writing.
The four RSV bits are undefined when read. Those bits should be masked after being read.
