[5] SYA CIRCUIT DESCRIPTION
1. Configuration and Functions
For the overall configuration of the SYA block diagram, refer to the block diagram. The configuration of the SYA block
centers around a 8-bit microprocessor (IC301). The 8-bit microprocessor handles the following functions.
1. Operation key input, 2. Mode LCD display, 3. Clock control, 4. Power ON/OFF, 5. Storobe charge control
Strobe charge voltage input (analog input)
