Function and Operation
50,51
C1D1, C1D2
O
Output pin for indicating the C1 error correction results
52-54
C2D1-C2D3
O
Output pin for indicating the C2 error correction results
55
D.VDD
Supplies current of positive voltage to the logic circuit
56
SFSY
O
Outputs 1 word of the subcode. Generally, 1 cycle is approx 136 micro seconds
57
SBSY
O
The signal indicates the beginning of the subcode block. The SFSY signal is
output at high level every 98 times
58
SBSO
O
Output pin for the subcode data
59

Input pin for the clock signal for read-out of the subcode data
60
A.GND
GND for the analog circuit
61
MD
O
Output pin for the spindle drive
62
SD
O
Output pin for the sled drive
63
TD

75
VR1
I
The signal input through these pins is digitized to 8-bit by the A/D converter,
which by operation of the assigned register, can be read into the microcomputer
76
FE
I
Inputs a focus-error signal from the RF amplifier
77
TE
I
Inputs a tracking-error signal from the RF amplifier
78
TEC
I
Input pin for the tracking comparator
79
REFOUT
O
