2. Internal Communication Bus
The SY1 circuit board 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 commu-
nication between the 8-bit microprocessor and ASIC.
