System Controller for Compact Disc Players
Description
The CXP1042Q is a 4-bit single chip microcomputer
based on the SPC500 series. It incorporates programs
in firmware for CD operations. It can be connected
directly to the CDL-500 series of LSIs for CD players,
and can directly drive LCDs, in addition to other features.
It can be employed in a wide range of equipment, from
deck-type CD players to radio cassettes and portable
systems.

INTRO
• 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.

The tray switch is determined according to the state where Pin 2 (PY1/MODE) and Pin 16 (PC3/KI3) is
connected immediately after reset or not.
Connected: DSP expansion port used
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
CXD2508A is employed for DSP.
Therefore, select the suitable method for the used DSP.
CXD2508A: DAC mute selected

Combination mode is set when Pin 2 (MODE) and Pin 13 (KI0) is not connected with diode.
In this time, combines the function.
2. REP key combination mode
Combination mode is set when Pin 2 (MODE) and Pin 14 (KI1) is not connected with diode.
In this time, REP combines SHL and PRG functions.

List of Functions
1. Deck/Portable select Switches between deck mode and portable mode. In deck mode the tray
loading function is activated; in portable mode, the battery detection
function is activated.
2. Remote control input Accepts signals from a NEC format remote control unit. A 16-bit custom
code can be selected.
3. Keys to initiate playing can be selected.
4. Performs tune selection.
5. Performs fast-forward and rewind. The speed differs during Play and Pause.
, , ,
,
,
6. Remain Can display Single Remain, All Remain, Program Remain.
7. Repeat For repetition of one or of all tunes.
8. A←→B For performance of A←→B repeat.
9. Shuffle Performed shuffled (random) playing.
10. AUTO Inserts 4-second blanks between tunes.
11. INTRO Plays the initial 10 seconds of a disc.
