10 / 28 page – 10 – CXP1021Q 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: • The relation between Pin 40 (UNLOAD/Batt-W) and Pin 39 (LOAD/DECK-PT) is as follows. (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. 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 State Open (stopped) LOAD direction UNLOAD direction H H L H L H Pin 40/UNLOAD Pin 39/LOAD LOAD direction UNLOAD direction Tray |
