21
O
22
V/P
O
Rough servo/phase control automatic switching monitor output. If a high level then rough servo mode. If a low level then
phase control mode.
23
HFL
I

24
TES
I
Tracking error signal input. Schmidt input.
25
TOFF
O
Tracking off output.
26
TGL
JP
+
JP
O
Tracking gain switch output. Gain is increased with low level.
27
O
Track jump control output. Can be 3-state output depending on the command.
28
O
29
PCK
O
EFM data playback clock monitor. 4.3218 MHz during phase lock.
30
FSEQ
O
Sync signal detect output. A high level when the sync signal detected from the EFM signal matches the internally
generated sync signal.
31
V
DD
P
Digital system power supply.
Reset signal input for initializing only the anti-shock control part (i.e. excluding the DSP part). Resets when this
pin is low level, and release the reset when this pin is high level. Tie this pin to the low level (i.e., connected to 0 V) if
when using software control on the anti-shock part alone through the anti-shock part only reset disable/release
I(I/O) command ($F4) or the anti-shock only reset enable/inrush command ($F5).
Note: This pin is assigned as the least significant bit of the general I/O port however, use as a general I/O
pin is disabled. When the port I/O set command ($DB) is executed, the least significant bit is always “0,” and the
output driver is not turned ON.
32
ASRES
33
CONT2
I/O
General I/O pin 2. This controls the commands from the microcontroller. When not used, either set this as an input
port and connect to 0 V, or set this as an output port and leave it open.
