Other Interrupt
Processes
Set Alarm Min., Hr., and
Day-of-week Registers
WAFG or DAFG=1
Conduct Alarm Interrupt
Yes
No
Control Register 2
(X1X1X101)
Generate Interrupt to CPU
*1)
WALE or DALE
0
*2)
WALE or DALE
1
*1) This step is intended to once disable the alarm
interrupt circuit by setting the WALE or DALE bits
to 0 in anticipation of the coincidental occurrence
of a match between current time and preset
alarm time in the process of setting the alarm
interrupt function.
*2) This step is intended to enable the alarm
interrupt function after completion of all alarm
interrupt settings.
*3) This step is intended to once cancel the alarm
interrupt function by writing the settings of
"X,1,X, 1,X,1,0,1" and "X,1,X,1,X,1,1,0" to the
Alarm_W Registers and the Alarm_D Registers,
respectively.
