The drive phase 1. The colon always flashes at 1 Hz rate.
3. OSC circuit
By connecting a resistor and a capacitor with the CR INPUT pin, a 2.4 kHz OSC circuit is formed, The
clock signal generated by the 2.4 kHz OSC circuit is used in the following cases.
(1) Used as the clock signal for the time counter, instead of 50/60 Hz INPUT, when the power-down mode
is entered.
(2) Alarm sound (1200Hz or 600 Hz) at the alarm signal output mode.
(3) 1/25 duty clock signal while the dimmer is in operation.
4. Power-Down Mode
(1) Since the backup OSC circuit holds the current time, the SC8562 starts operating immediately.
(2) The snooze function stops operating.
(3) The RADIO pin is brought to the OFF state.
(4) The control input is inhibited (except the following).
OFF INPUT
ALARM/SLEEP TIME SET INPUT at the time setting enable mode
5. Alarm
The SC8562 contains two alarms on a 24-hour basis.
Alarm 1… .. Superposition of 600 Hz and 1 Hz
Alarm 2 … . Superposition of 1200 Hz and 1 Hz
6-minutes snooze
The alarm output duration time is 59 minutes. The 59-minute duration counter is common to the alarm 1,
alarm 2, and sleep timer.
6. Time Setting, Dimmer
The 3-level input TIME_SET pin provides the following operations.
