4. Power Supply ControlThe 8-bit microprocessor controls the power supply for the overall system.The following is a description of how the power supply is turned on and off. When the battery is attached, a regulated 3.2 Vvoltage is normally input to the 8-bit microprocessor (IC301) by IC302, so that clock counting and key scanning is carried outeven when the power switch is turned off, so that the camera can start up again. When the battery is removed, the 8-bit microprocessoroperates in sleep mode using the backup lithium secondary battery. At this time, the 8-bit microprocessor only carriesout clock counting, and waits in standby for the battery to be attached again. When a switch is operated, the 8-bit microprocessorsupplies power to the system as required.The 8-bit microprocessor first sets both the P (A) ON signal at pin (6) and the P ON signal at pin (5) to high, and then turns on theDC/DC converter. After this, high signals are output from pins (60), (61), (62), (63) and (64) so that the ASIC is set to the activecondition. If the LCD monitor is on, the LCD ON signal at pin (21) and the LCD ON 2 signal at pin (53) set to high, and the DC/DCconverter for the LCD monitor is turned on. Once it is completed, the ASIC returns to the reset condition, all DC/DC convertersare turned off and the power supply to the whole system is halted.ASIC,memoryCCD8 bitCPULCDMONITORPower voltage3.3 V5 V (A)+15 V (A) etc.3.2 V(ALWAYS)+15 V (L)CAMERAPower OFFPower switch ON-Auto power OFFShutter switch ONMonitor OFFOFF OFF 32KHz OFFOFF OFF 4 MHz OFFON ON→OFF 4 MHz OFFOFF OFF 4 MHz OFFLCD finderON ON 4 MHz ONPlay backON OFF 4 MHz ONTable 4-3.

During playback, the 16-bit D/A circuit converts these signals into analog audio signals.– 8 –
