(2) Program ROM

Program ROM contains a program for the equipment. EPROM is used as program ROM.
When mask ROM in the one-chip CPU explained in (1) above is valid, the EPROM is not
mounted. (For details on short wiring setting, see Section 7.2.)

(3) DRAM

DRAM is used as resident memory.

(4) EEPROM

EEPROM holds the following data:
• Menu data
• Counter value
• Adjustment value

(5) Parallel interface

The parallel interface receives parallel data from the host; it conforms to the IEEE1284
specification.
