Initialization
Reg1Dh
Clear VLF bit to “0”.
State of VLF=1 is held even if it 0 clear until oscillation start. When initialize
it without waiting for an oscillation start, Clear VLF bit after an oscillation
start.
Reg1Fh
Set INIEN to 1.
When it is used in INIEN=0, please set it in INIEN=0 again after setting
INIEN to 1 once.
Set time and
calendar.10h16h
Set the present time.
Setting the present time concerned.
See 14.1. Clock calendar explanation.
Alarm function
Configure the Alarm interrupt function.
When the alarm interrupt function is not being used, the Alarm registers
can be used as a RAM register. In such cases, be sure to write "0" to the
AIE bit.
Interval timer function
Configure the interval timer function.
When the interval Timer function is not being used, the Timer Counter
register can be used as a RAM register. In such cases,
stop the interval timer function by writing "0" to the TE and TIE bits.
When initialization is finished, be sure to set STOP bit to “0”.
Reg1Ch
Clear TE bit to “0”.
Set FSEL1,0 bitoptionally.
Update interrupt function
Configure the Update interrupt function.

Setting of the digital offset
Reg30h
 When the digital offset function is not being used, write 0 in the DTE bit.
Reg1Eh
Clear TEST bit to 0.
Clear AIE, TIE, UIE for inhibit interrupt output of suddenness.
