A signal to cause emission of the LD from MCU PCB to LD assy
(LD ON(L) 3.7 V DC)
Monitoring of output to LD based on data (for adjusting LD power)
Adjusts LD power.
LD power voltage of ROS assy's LD
Controls scanner motor revolution. SPI 1="H", SPI 2="L" for a resolution of 300 dpi
Start reference signal for scanning by ROS assy's scanner motor based on a laser
beam entering into SOS sensor
