/ 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.

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. Accepts signals from a NEC format remote control unit. A 16-bit custom code can be selected. Keys to initiate playing can be selected. Performs tune selection. Performs fast-forward and rewind. The speed differs during Play and Pause. Can display Single Remain, All Remain, Program Remain. For repetition of one or of all tunes. For performance of A repeat. B Performed shuffled (random) playing. Inserts 4-second blanks between tunes. Plays the initial 10 seconds of a disc. Enables programming of up to 21 tunes. Enables direct tune selection using the keypad (for use with a remote control unit only). A function for detection of reduced battery voltage is provided by the BattW and Batt-E pins (portable mode only). For sync rate input and activation. , Double-speed playback is executed only when key is set to the independent mode and REP key to repeat key if sync rate input is made for stop. With the deck mode selected, tray loading is possible. The tune select and fast-forward keys can be combined or kept independent, and the repeat key and mode key can be selected.

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 Pin 19 (UNLOAD/Batt-W) goes "H" when tray is ejected Pin 20 (LOAD/DECK PT) goes "H" when tray is closed For the tray SW Disc IN goes "L" when the tray is closed Disc OUT goes "L" when tray is fully opened
Tray
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. State Open (stopped) LOAD direction UNLOAD direction Close completed (stopped) Pin 19/UNLOAD H L H H Pin 20/LOAD H H L H
(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. - 10 -

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. Timing chart for mute on

(Example: custom code "1234") By forming a diode matrix, a single bit of data is created; adding a diode at each point sets that point to "0". Please use the above example as a reference. This matrix is read only immediately after the power is turned on.
The data on the receiving end is as shown above and cannot be changed. For the transmitting end, please refer to the specifications of the transmitting side chip.
