I/O
Function and Operation
38
LOCK
O
Indicates "H" when the synchronized pattern detection signal matches the
frame counter output at the EFM recovery modulation, and "L" when they
don't match
39

Minute-cycle signal for the bit clock, the signal indicates the cycle of 1 frame
(approx. 7.35kHz)
40
RFCK
O
Minute-cycle signal for the clock, the signal indicates cycle of 1 frame
(approx. 7.35kHz)
41
D.GND
GND for the logic circuit
42,43
TEST0,1
I
Test pins
44,45

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
