R2023K/T
Typical Software-based Operations
Initialization at Power-on
47
Start
*1)
Yes
No
VDET=0
Warning Back-up
Battery Run-down
Set Oscillation Adjustment
Register and Control
Register 1 and 2, etc.
Power-on
*2)
*4)
*3)
PON=1
Yes
No
*1) After power-on from 0 volt, the start of oscillation and the process of internal initialization require a time
span on 1to 2seconds, so that access should be done after the lapse of this time span or more.
*2) The PON bit setting of 0 in the Control Register 1 indicates power-on from backup battery and not from 0v.
For further details, see "P.36
PON,
XST
, VDET".
*3) This step is not required when the supply voltage monitoring circuit is not used.
*4) This step involves ordinary initialization including the Oscillation Adjustment Register and interrupt cycle
settings, etc.
Writing of Time and Calendar Data
Write to Time Counter and
Calendar Counter
*2)
Stop Condition
*3)
Start Condition
*1)
*1) When writing to clock and calendar counters, do not insert Stop
Condition until all times from second to year have been written to
prevent error in writing time. (Detailed in "P.28 Data Transmission
under Special Condition".
*2) Any writing to the second counter will reset divider units lower
than the second digits.
*3) Take care so that process from Start Condition to Stop Condition
will be complete within 0.5sec. (Detailed in "P.28 Data
Transmission under Special Condition".
The R2023K/T may also be initialized not at power-on but in the
process of writing time and calendar data.
