IC DESCRIPTION - 1/6 (µPD784216AYGC-105-8EU) - 1/3
Goes "H" to start charging.
Outputs one-shot "L" (approx. 50 ms) to turn off the CD system power.
Outputs one-shot "H" (approx. 50 ms) to turn on the CD system power.
Reset output to LCD driver
Clock output for transferring serial data to EASS controller
Serial data output to EASS controller
Serial data output latch to EASS controller
SENS input from EASS controller
Power supply
Clock pin
Clock pin (6.25 MHz)
GND
Sub-clock pin
Sub-clock pin (not used and connected to GND)
Reset input
Interrupt request input from ROM decoder
DRG signal input from ROM decoder
Wakes up when remote control key is accepted ("H" is input when a key is pressed)
SCOR input from DSP
PLAY key input: The key is detected at "L". This also wakes up when the edge from "H" to "L"
is detected in the sleep mode.
STOP key input: The key is detected at "L". This also wakes up when the edge from "H" to "L"
is detected in the sleep mode.
Lid open/close detection. This also wakes up when the edge is detected ("H" -> "L" or "L" ->
"H") in the sleep mode. "H" : OPEN, "L" : CLOSE.
Power supply of A/D converter
Reference power supply of A/D converter
Main-unit key A/D input 2 (see separate sheet)
Remote control key A/D input (see separate sheet)
Main-unit key A/D input (see separate sheet)
RESUME, HOLD SW A/D input (see separate sheet)
CD system power voltage monitoring: Input when the voltage is 100/133=75.2%
MP3 system power voltage monitoring: Input when the voltage is 100/133=75.2%
Battery voltage monitoring during charging (see separate sheet)
Input when the voltage is 0-3.0 V x 90.9% (microprocessor input voltage), or 2.5-3.5 V (battery
voltage).
Input when the voltage is 75.2% of battery voltage monitoring pin (see separate sheet). The
voltage input to this pin causes the battery remaining level display or "Lo-Batt" display.
GND
MP3 power supply control. H": ON; "L": OFF
