3、serial communications withthe main unit control section, the key input circuit, the dis-play circuit, and the dimmer circuit through the microproces-sor (IC4).a73 Serial communications circuitA buffer amp is inserted in order to protect the micropro-cessor ports.a73 Key, Volume input circuitCircuits

4、 to operate the panel section keys are connectedto each microprocessor port. The PSW key is pulled up andthe other keys are pulled up with software within the micro-processor. Rotary encoder operating circuits are connecteddirectly to the microprocessor. The control divides thepower supply voltage,

5、reads the A/D port of the micropro-cessor, and transfers that data to the main unit.a73 Display circuitDisplay section is a 188 x 54-dot full-dot matrix LCD con-trolled by two LCD. As shown is Figure 1, the master IC(IC2) side is connected to 22 common dots and 88 segmentdots and the slave IC (IC1)

6、side is connected to 33 commondots and 100 segment dots. The LCD drive voltage is ob-tained by raising the power supply voltage (5V) within the IC.a73 Dimmer circuitThe dimmer circuit switches the lamp brightness to oneof four levels or OFF (See table1). The current flowing to theLEDs is varied by s
