functions.
• NEC format remote control input possible; index serch, direct tune selection through keypad and other
functions can be added.
• Supports auxiliary functions including synchronization input, double-speed output and pitch control.
• 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.
• A built-in test mode facilitates adjustment of the CD player and can be used for tests and evaluations.

1. Deck mode/portable mode selection
A feature of the CXP1021Q is its ability to be used in both deck-type and in portable equipment.
(a) Selection
Selection is executed through Pin 39 (LOAD/DECK-PT). Mode selection is determined by the condition of
this pin immediately after reset of the CXP1021Q.
When Pin 39 (LOAD/DECK-PT) is high: Deck mode
When Pin 39 (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 40 (UNLOAD/Batt-W)
goes "L" when tray is ejected
Pin 39 (LOAD/DECK PT)
goes "L" when tray is closed
Pin 37 (Disc IN) goes "L" when the
tray is closed
Pin 38 (Disc OUT/Batt-E) goes "L"
when tray is fully opened
For the tray SW

(c) Portable mode
• In portable mode, when the lid is closed the operation changes to TOC reading.
• Pin 39 (LOAD/DECK-PT) should be held "L".
• Pin 37 (Disc IN) 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 40 (UNLOAD/Batt-W) is made "L" through the reduced voltage detection circuit, BATT is
displayed.
• In addition, when Pin 40 (UNLOAD/Batt-W) is "L", forcing Pin 38 (Disc OUT/Batt-E) "L" induces the STOP
state.

2. Key combination selection
This function can be used to reduce the number of keys needed.
(a) Selection
Selection is made through Pin 61 (KEYSEL). Selection is determined by the state of this pin immediately
after reset of the CXP1021Q.
When Pin 61 (KEYSEL) is high: keys are combined.
When Pin 61 (KEYSEL) is low: keys are independent.

Description of Operation
20. Test Mode
Branching to Test mode is achieved by setting Pin 62 (TEST IN) to "L". When Pin 62 (TEST IN) is set "L" and
Reset Start is executed, focus searching is repeated at the current pickup location.
If a disc is loaded, the focus is turned on, the CLV-A and tracking sled servo are turned on, mute is turned off,
and play is begun.
→In deck mode, the OPEN key can be used to operate the tray. When the tray closes, focus searching is
begun.
→In portable/radio cassette mode, operation does not begin until the lid is closed. When the lid is closed, focus
searching is begun.
(a) Focus bias
When reset is executed without a disc loaded, the lens is moved up and down in approximately one
second intervals.
(b) Running check
When reset is executed with a disc loaded, focus searching, focus on, CLV-A, and tracking sled servo are
set on, mute is turned off, and play is begun. At this time, the following key operations are possible.
= All servo off
, ,
= Repeated focus searching. When a disc is loaded, play is begun.

= CLV-A, tracking off, sled off
= Fast-forward 200 track jump (during play only)
= Fast-rewind 200 track jump (during play only)

Three-state output selected for SC pin. As a result there are constraints on tsys, and caution should be
exercised in prescribing an upper limit to the system clock frequency fc.
