Function
System Power 1 control terminal
When ACC control terminal (45 pin) is "H" (ACC
control from the head unit is "L"), or when ACC
control terminal is "L,” the eject key is “ON,” and
when the magazine is inserted, this terminal becomes
“H" and supplies power to the system.
System Power 2 control terminal
This port becomes “H” when the auto changer is ON
and supplies power to CD 1C: CXD2545.
Turns to "L" after spindle motor stops in stop mode,
and turns off the power of CD iC.
Terminal to control audio relay of external switch box
Controlled by C-BUS command. Normally "H" is
output when the auto changer is in play mode.
laser output control
°L": Laser "ON"
C-BUS/service request output terminal
When the slave CPU wants the master to read the
data to inform status change, "H" is changed to "L.”

Eject key input terminal
By inputting "L”, executes magazine eject operation.
Even when u-COM is in stop mode, cancels the stop
mode with the input of eject key, and executes
magazine eject operation..(When EJSEL 31 pin: "H")
TEST MODE | (operation by KEY) selection terminal
By inputting “L” when starting CPU, switches to TEST 1.

By inputting "L" when starting CPU, switches to TEST 3.
When switched to TEST { and TEST 2, operates by
key inputs from 27-, 28-, 29-, and 30-pi

31 | EISEL When ACC is OFF and each eject key is "ON" in
"H" mode, each eject operation is possible. Operation
prohibit is activated in "L" mode.

ACC Control input terminal. By inputting "H" or "L"
when ACC is ON, »-COM turns to stop mode to stop
the clock. If "L" — "H" is detected in that condition,
the stop mode is canceled and p-COM moves to the
operation mode after clock vibration is stabilized.
Magazine insert detection switch input terminal
"L": Inserted, When t-COM is in stop mode and the
magazine is inserted, the stop mode is canceled and
disc check is carried out.
