Circuit Description

WorkCentre Pro 412
Launch Issue

5-11

August 2001

5-2-4 Program ROM (Flash Memory) Control

1) Device
Type No.

AM29F800B

Capacity

4 Mbyte (512K * 16BITS * 4)

2) Programming
Before assembly

EPROM programmer or programming at the factory

After assembly

Download from PC

3) Operating Principle
When the RCSO(ROM CHIP SELECT) signal is activated from the CPU after the POWER is ON, it activates
RD SIGNAL and reads the DATA(HIGH/LOW) stored in the FLASH MEMORY to control the overall system.
The FLASH MEMORY may also write. When turning the power on, press and hold the key (power switch) for
2 - 3 seconds, then the LED will scroll and the PROGRAM DOWNLOAD MODE will be activated. In this
mode, you can download the program through the parallel port.
