3.Functions
a. When the clock is disable, the alarm is disable.
b. The alarm is enable when power is on and power is off.
c. If the ALARM key is pushed. The alarm adjusting enable state is set for 5 seconds, and the alarm times flash
at 1 Hz rate.
In that state, the hour of the alarm is adjusted by pushing the UP/HOUR key, and the minute of alarm is
adjusted by pushing the DOWN/MIN key.
d. If the any keys are not pushed for 5 seconds, the alarm adjusting enable state will be released.
e. When the MEMORY/CLOCK-ADJUSTMENT key is pushed in the alarm adjusting enable state, that state is
released and alarm times is changed flash to on. So if the any keys are not pushed 5 seconds, the alarm
display state is released.
f. The hour or the minute step up by 1 step/ 1 push, if the key is pushed for less than 500ms in alarm adjusting
enable state.
If the key is pushed more than 500 ms in this state, the hour step up continuously by 1 step/ 250ms, the
minute step up continuously by 1 step/150ms.
g. If alarm time comes same to clock time, the alarm sound is output by BUZR (p3-1) port. In that state if the any
keys are pushed, the alarm sound is released. But if the any keys are not pushed, the alarm sound is output
for 60 minutes.
