∗/∗∗ Multiple functions can be combined.
• LCDs can be driven directly. This includes time display, music calendar, remaining tunes and other display
functions.
• NEC format remote control input possible; direct tune selection through keypad and other functions can be
added.
• Supports auxiliary functions including synchronization input and double-speed playback.
• Easy switching between deck and portable equipment using external pins.
(i) With deck type selected, performs tray loading function.
(ii) With portable type selected, displays detection of weak battery and executes emergency termination
when battery voltage is low.
In this way, it functions specific to the system required.
• An simple tracking gain/balance function is built-in, enabling adjustment of the tracking gain/balance
according to the disc.

connected immediately after reset or not.
Connected:

Not connected: Microcomputer port used
However, use the microcomputer port when the OPEN/Batt-E function is employed for portable mode.
The selected mute (Pin 2 (PY1/MODE) or Pin 15 (PC2/KI2)) is used to identify which of the CXD2507A or

CXP1042Q
1. Deck mode/portable mode selection
A feature of the CXP1042Q is its ability to be used in both deck-type and in portable equipment.
(a) Selection
Selection is executed through Pin 20 (LOAD/DECK-PT). Mode selection is determined by the condition of
this pin immediately after reset of the CXP1042Q.
When Pin 20 (LOAD/DECK-PT) is high: Deck mode
When Pin 20 (LOAD/DECK-PT) is low: Portable/radio cassette mode
(b) Deck mode
• In deck mode the tray loading function is activated.
• Pins necessary for tray operation:
For the loading motor
Tray
For the tray SW
Pin 19 (UNLOAD/Batt-W)
goes "H" when tray is ejected
Disc IN goes "L" when the tray is
closed
Pin 20 (LOAD/DECK PT)
goes "H" when tray is closed
Disc OUT goes "L" when tray is fully
opened
UNLOAD direction
LOAD direction
The tray switch state is input from the microcomputer port or DSP port according to the microcomputer
operation mode.
• The relation between Pin 19 (UNLOAD/Batt-W) and Pin 20 (LOAD/DECK-PT) is as follows.

(c) Portable mode
• In portable mode, when the lid is closed the operation changes to TOC reading.
• Pin 20 (LOAD/DECK-PT) should be held "L".
• Pin 11 (Disc IN/OPEN) should be connected to a switch that makes the pin go "L" when the lid is closed.
• Two pins used in deck mode can be employed to detect a reduced battery voltage.
• When Pin 19 (UNLOAD/Batt-W) is made "L" through the reduced voltage detection circuit, BATT is
displayed.
• In addition, when Pin 19 (UNLOAD/Batt-W) is "L", forcing Pin 12 (Disc OUT/Batt-E) "L" induces the STOP
state.
• Input the Disc IN/OPEN and Disc OUT/Batt-E to the microcomputer port because the DSP expansion port
can not be used for the portable mode.
(d) Selection of tray switch input port
The microcomputer port or DSP port can be selected for the tray switch input (Disc IN/OUT) according to the
state where Pin 2 (MODE) and Pin 16 (KI3) is connected immediately after reset or not.
Not connected:
Microcomputer port used
Connected with diode: DSP port used
However, use the microcomputer port when the OPEN/Batt-E function is employed for portable mode.

3. Mute function
The CXP1042Q has two mute pins, Pin 17 (MUTG...active high) and Pin 18 (MUT2...active low).
The command transferred to the DSP and the state of mute pin differ depending on the selected mute method
when mute is turned on.
• DAC mute (CXD2508A used)
When "mute on" is requested, set Pin 18 (MUT2) active and then transfer the attenuate command (A00000h)
to the DAC.
Only when "open/stop" is requested, set Pin 17 (MUTG) active after approximately 32ms from the command
transfer.
• DSP mute (CXD2507A used)
When "mute on" is requested, set Pin 17 (MUTG) and Pin 18 (MUT2) active and then transfer the mute
command (A207F0h) to the DSP.
Note that A007F0h is transferred when mute is turned off both for DAC mute and DSP mute.
