Operation Description
1.
Segment Output
The duplex LED panel can be direct driven by 13 segment output pins.
(Compatible with LM8560-use LED panel)
2.
Colon Output
LED panel
The drive phase is 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 (1200 Hz or 600 Hz) at the alarm signal output mode
(3) 1/25 duty clock signal while the dimmer is in operation
Power-Down Mode
(1) Since the backup OSC circuit holds the current time, the LM8562 starts operating immediately.
(2) The snooze function stops operating.
(3) The RADIO OUTPUT pin is brought to the OFF state.
(4) The control input is inhibited (except the following).
