R2033K/T
Typical Software-based Operations
Initialization at Power-on
46
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.35
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)
CE
←
L
*3)
CE
←
H
*1)
*1) When writing to clock and calendar counters, do not insert CE=L
until all times from second to year have been written to prevent
error in writing time. (Detailed in "P.24
Considerations in
Reading and Writing Time Data under special condition".
*2) Any writing to the second counter will reset divider units lower
than the second digits.
The R2033K/T may also be initialized not at power-on but in the
process of writing time and calendar data.
