LC5824, LC5823, LC5822
Circuit type
Notes
RC & Xtal
Divider
• The cycle time is 4 times the f1 period.
• The divider circuit outputs (ø1 through ø15)
are used as the clock time base, the LCD
drive waveform generation clock, and for
S/K port chattering prevention.
• OSC1 is stopped by the execution of a
SLOW instruction.
CF & Xtal
• 400 kHz (CF)
• 4 MHz (CF)
Divider
• The cycle time is 4 times n times the f1
period. (n:1)
• The divider circuit outputs (ø1 through ø15)

drive waveform generation clock, and for
S/K port chattering prevention.
