DATA WRITE (CPU 3 LCD)
The voltage is supplied by the printer head power source, passed through
the printer, and divided by the resistor is inputted to AN1 pin.
LRS
The A/D conversion value must be read after turning VHCOM signal
(CPU P106) to "H" and stabilizing the voltage (after 10msec).
LR/W#
The printable voltage range of the printer is 15V~26V. The voltage is
calculated from the AN1 value and the A/D conversion value of the reference voltage.
