Internal Communications Paths
The SYA block detects input from the control keys and the status of the camera's circuits and controls the overall camera.
Signals from the various detectors are read by the 8-bit microprocessor as input data and then output to the camera circuit
(ASIC) as operation mode settings information.
Figure 3-3 shows the 8-bit microprocessor and ASIC connections.
