DSPSEL
ON when DSPSEL output by commander is high.
Determines
timing
for
data
output
from
master
microcomputer to commander.
Output begins at the
edge of going from ON to OFF, so when OFF, output
can not be done.
In accessory ON state, the program stops unless there
is DSPSEL input signal.

ely
de Wee
Control output to elevator control motor (M3) control IC.
TPACK
Judges whether tuner is connected or not.
Only monitors the switch during accessory ON.
BU
Checks
backup
voltage.
Goes
ON
when
voltage is
high.
HOT
Goes ON when temperature is too high.
When it goes ON, the same operation occurs as when
the ALL OFF key is pressed.
No keys, except for EJECT, are accepted while it is
ON.
LOT
ON
during linear slide lever operation,
OFF
when
operation ends,
PST
ON when pack is in.
CBP
Detects pack lever, and returns disc to that position
when ON.
— CD-27 —
EJT
Goes ON when pack ejection is completed.
EJKEY
EJECT KEY input; always accepted except for during
reset processing and pack setting.
HOME
Home
switch detection; only performs home switch
detection for reset processing and elevator control.
1C€507 Pin Functions
DOE
Detects if disc is in or not for reset processing and
LOAD processing.
DPT
Detects
if disc was
in or not for reset processing,
LOAD processing and SAVE processing.

Commander reset signal output.
Mechanism control microcomputer (IC504), IC501,
etc. reset signal output.
Outputs high after chucking is completed, turns IC504 power on
then outputs low 200 msec later.

DRS ON at high.
8
DRS2 when both pins (6) and (8) are high.
IC504, etc. power supply control and output fro tuner and DC signal switching.
Outputs low except
for when CD signal switching.
Output low except for when CD is in PLAY or PAUSE.
Ground
Remote output.
LED drive for display during PACK reset.
BEEP output.
Outputs high for about 32 msec.
Reset signal input.
L: reset
When this pin is made high, internal register state is shifted to latch.
Serial data input pin.
Clock input pin. Takes data in at rise.
Power supply in +5 V.
