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)
