For the power supply for this system, the VD (7.5 ± 0.5 V) and the VDD (5.0 ± 0.25 V), which are supplied from the
motherboard, are used. The three power supplies, the VD mentioned above (for the drive system), the V3R3D obtained
from the VD via the 3.3 V regulator (for the control system: 3.3 V) and the VDD (for the microcomputer: 5 V), are used in
this system.
The microcomputer controls ON/OFF with "CONT", except for Load/Eject of the CD driver, and ON/OFF of 3.3 V with
"CD3VON". For ON/OFF of the Loading drive, no particular control terminals are available, but the input signal "LOEJ"
assumes an equivalent role. Also, the LCO output switches LOADING MODE and CARRIAGE MODE with "CLCONT".
