3. CPU (HB/3040)
A. Outline
The CPU (IC3) controls finisher loads and the system synchronously,
transmitting and receiving data to and from the copier main PWB
through the serial communication line.
B. Features
The H8/3040 is a high-performance single chip microprocessor using
the 32-bit H8/300H CPU as a core, integrating peripheral functions
necessary for system configuration.
The H8/300H CPU has an internal 32-bit configuration and is
equipped with 16-bit
×
16 general-purpose registers and a simple,
optimized instruction set for high-speed operation. It can handle 16M
byte linear address space.
As peripheral functions, it contains ROM, RAM, 16-bit integrated timer
unit (ITU), programmable timing patter controller (TPC), watchdog
timer (WDT), serial communication interface (SCI), A/D converter,
D/A converter, I/O port, DMA controller (DMAC), and refresh control-
ler.
