2. Internal Communication Bus
The SY-A block carries out overall control of camera operation by detecting the input from the keyboard and the condition of the
camera circuits. The 8-bit microprocessor reads the signals from each sensor element as input data and outputs this data to the
camera circuits (ASIC) or to the LCD display device as operation mode setting data. Fig. 4-1 shows the internal communication
between the 8-bit microprocessor, ASIC and SPARC lite circuits.
