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. Operation key input, 2. Clock control and backup, 3. Power ON/OFF, 4. Storobe charge control, 5. Signal input and output for
zoom and lens control.
