Function and Operation

Remarks

69

RFGC

Control signal output pin for adjusting RF

amplitude.

Outputs three-level PWM signal

(PWM carrier

= 88.2 kHz).

70

TEBC

Tracking balance control signal output pin.

Outputs three-level PWM signal

(PWM carrier

= 88.2 kHz).

71

FMO

Focus equalizer output pin.

Outputs three-level PWM signal

(PWM carrier

= 88.2 kHz).

72

DMO

Disc equalizer output pin.

Outputs three-level PWM signal

(PWM carrier

= 88.2 kHz for DSP block).

SEL

CD processor control

input/output

APC circuit on/off signal output pin.

At laser on, high impedance at UHS

= High; H

level output at UHS

= High.

77

XVSS

80

XVDD

Power supply pins for CD crystal oscillator.

To control the CD processor power supply

and the controller power supply individually,

connect the MVDD and MVSS pins to the

power supply lines used by the VDD and VSS

pins.

XO

CD processor crystal

oscillator pins

CD crystal oscillator input/output pins.

Connect a 16.9344 MHz crystal oscillator. The

clock is used as the CD system clock and

controller system clock.

After system reset, this clock is supplied as

the controller system clock and starts the

CPU.

The crystal oscillator can be halted by

program. If the 4.5 MHz or 75 kHz oscillator is

selected as the controller system clock, the

oscillator is halted by program when the CD

processor is off.

During execution of the CKSTP instruction,

oscillation halts.

(Note)

When switching the controller

system clock from the controller

oscillator to the CD crystal oscillator,

make sure that the CD crystal

oscillator is in stable state.
