The output voltage in which the power supply that diverges from the BU1.5V line
is turned on and off is used as D1.5V.
The output voltage in which the power supply that diverges from the BU3.3V line
is turned on and off is used as D3.3V.
Because the detection logic of LOE/LIM_SW is different in the mechanism μ-COM
and the system μ-COM, the logic to the mechanism μ-COM side is reversed.
Prevents reverse bias which is applied to laser.
Laser destruction prevention.
The potential difference between DGND and AGND is absorbed, and the malfunc-
tion by static electricity is prevented.
