1. SYSTEM CONTROL CIRCUIT
1-1. Overview
The DSC-F55/F55E system consists of two microprocessors (Human In-
terface (HI) Controller IC603 and Camera/Medium Controller IC351).
(IC501 is an auxiliary IC for serial communication between the control-
lers.)
The data transfer system between the controllers and block diagram are
shown in Fig. 1-1.
Communication between the HI microprocessor (abbreviated as “HI Con-
troller” hereafter) and the camera/medium microprocessor (abbreviated as
“CAM/MEDIUM Controller” hereafter) is established using clock synchro-
nous serial communication.
When the HI Controller detects any key input, it sends the corresponding
mode command to the CAM/MEDIUM Controller in accordance with the
contents of key input.  At the same time, the status of the camera block and
other blocks are always sent to the HI Controller.  The HI Controller con-
trols the operating mode of the DSC-F55/F55E.  The control data of the HI
Controller is saved in IC456 (EEPROM) and that of the CAM/MEDIUM
Controller is saved in IC457 (EEPROM).
