2. Circuit descriptions
A. Main PWB (MCU)
(1) General
The MCU PWB is composed of: 
•CPU peripheral section which performs mechanical sequence
control, U/I, and each function job management.
The CPU connects with the ASIC and memory by use of the system
bus and performs jog management and sequence control of the
whole engine.
•Image process ASIC which performs image process, CCD control,
LSU control, and print control.
•OA982 peripheral section which...

(3) Image process ASIC (HG73C114HF)
a. General
The ASIC is composed of the three blocks: the image process block,
the print control block, and the I/F block.
Image process section
According to the operation mode set by the register set value, the
image data from the CCD PWB are placed under shading, AE pro-
cess, input gamma process, area separation, filter process, resolu-
tion conversion, zoom process, output gamma process, and binary
coding.
