7-12 DVD System Control
(1) Outline
The main micom peripheral circuit is composed of 4M EDO ROM (SIC2) for Microcode and data save, 2Kbit
EE-PROM (ZIC7) for permanent storage of data needed at power off, 64Mbit SDRAM (ZIC2) for temporary data
read and write.
The Micom (ZIC1, Vaddis 5E) mounted in main board analizes the key commands of front panel or instructions of
remote control through communication with Micom (IC601 ; MN101DF06) of front and controls the devices on
board to execute the corresponding commands after initializing the devices connected with micom on board at
power on.
