3.2.1 Logic Components
[1] CPU (M30622M8)
The CPU (#1) is a 16-bit microprocessor manufactured by Mitsubishi Electric
Corp., which controls and manages the entire system.
This CPU has a 64-Kbyte internal ROM which stores all programs. The
internal RAM has 4 Kbytes.
[2] RAM (SRAM)
A 128-Kbyte SRAM (#5) is used as a data buffer.
[3] ROM (EEPROM)
A 1-Kbit EEPROM (#9) is used, into which baud rate,vendor ID code,product ID
code and mechanical information is written to be stored.
After the main PCB assy has been replaced ,the serial number shown on the
main body and model name (PT-9200DX) must be stored in the EEPROM on
the main PCB. To do this, Fig.3.2.-2 shows connect the PC with PT-9200DX
via a serial I/F cable, and use special software supplied separately. For details,
refer to section 3.4 description of model name and serial number writing
software.
