  • Page 6 1-5. SYA CIRCUIT DESCRIPTION 1. Configuration and Functions For the overall configuration of the SYA block, refer to the block diagram. The SYA block centers around a 8-bit microprocessor (IC301), and controls camera system condition (mode). The 8-bit microprocessor handles the following functions. 1.

  • Page 8 4. Power Supply Control The 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 V voltage is normally input to the 8-bit microprocessor (IC301) by IC302, so that clock counting and key scanning is carried out even when the power switch is turned off, so that the camera can start up again.
