(3) Applied Process of Reading Time and Calendar Data with Periodic Interrupt Function
Time data need not be read from all the time counters when used for such ordinary purposes as time count
indication.
This applied process can be used to read time and calendar data with substantial reductions in the
load involved in such reading.
For Time Indication in "Day-of-Month, Day-of-week, Hour, Minute, and Second"
Format:
*2)

CTFG=1?
Control Register 2

(X1X1X011)
Yes
Read Min.,Hr.,Day,
and Day-of-week
*4)

Control Register 1
←
(XXXX0100)
Control Register 2
←
(X1X1X011)
Use previous Min.,Hr.,
Day, and Day-of-week data
*1) This step is intended to select the
level mode as a waveform mode for
the periodic interrupt function.
*2) This step must be completed
within 0.5 sec.
*3) This step is intended to read time
data from all the time counters only in
the first session of reading time data
after writing time data.
*4) This step is intended to set the
CTFG bit to 0 in the Control Register
2 to cancel an interrupt to the CPU.
