Software

1

PLL

Division mode 2 types

frequency

• Direct division mode (VCOL pin)

synthesizer

• Pulse swallow mode (VCOL and VCOH pins)

Reference

frequency

Seven types selectable in software (1, 3, 9, 10, 12.5, 25, 50 kHz)

Charge pump Error out output: 2 pins

comparator

Unlock detectable in software

Notes 1. When using the IEBus controller, the 4.5-MHz crystal resonator cannot be used. Use the 6.3-MHz

crystal resonator.

2. When the I2C bus mode is used (including when the mode is implemented in software without using

the peripheral hardware), consult NEC when ordering a mask.
