5-2 Major Functions of Each MI-COM
(1) FR MI-COM (IC2301 : VIC4)
The FR MI-COM, as the nucleus of the system, carries out control of mode transition plus mechanism control through communi-
cation with MODE MI-COM. It also detects of various sensors and switches (DMCIII). Following are the major functions.
• VIC (Video) control / AIF4 (Audio Interface) controls
• Control in accordance with IEEE1394
• USB interface control
• AUDIO control
• DMC III mechanism control
• DIGIC DV control
• Card control
• CCD drive control
• AE, AF, AWB control
• EIS (Electric Image Stabilizer) control
• OSD (On Screen Display) bitmap control
• PRINTER control
* The FR MI-COM in this machine does not have a dedicated EEPROM. Since a flash ROM is used for the FR
MI-COM as a substitute for the EEPROM, it is required to update the flash ROM after adjustment and data
modification regarding the FR MI-COM.
(2) MODE MI-COM (IC100)
The MODE MI-COM is mainly in charge of the power-on sequence and charging control. Following are the major functions.
• Key input
• LCD / EVF control
• Remote control input
• Power ON/OFF control
• Built-in charge circuit control
• MIC (Memory In Cassette) control
* The MODE MI-COM in this machine does not have a dedicated EEPROM. Since a flash ROM is used for the
FR MI-COM as a substitute for the EEPROM, it is required to update the flash ROM after adjustment and data
modification regarding the FR MI-COM.
