Signal flow:
1. Panel (refer to the block diagram, Fig. 2)
Input signals from CP1, CP2, CP3, CP5, PCON
Input to the A/D input port of the UI microcomputer
LED output and execution of communication with SC
LCD display, audio output, turntable rotation, etc.
2. LED (refer to the block diagram, Fig. 3)
Port output from the UI microcomputer (from data of the above switches etc.)
Data output to CP1, CP3, CP5, STROBE, etc.
Address serial data are concerted to the matrix and LEDs are lit.
