*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.
*1) This step is intended to select the level mode as a
waveform mode for the periodic interrupt function.
*2) This step is intended to set the CTFG bit to 0 in
the Control Register 2 to cancel an interrupt to the
CPU.
