3. Programming to the EPROM

Since the MB89P915 requires a special method for programming to its PROM, the types of general-purpose

EPROM programmers applicable to the MB89P915 are limited. Programming to the PROM on the MB89P915

requires an EPROM programmer applicable to the MB89P915 and a dedicated adapter.

When the operating ROM area for a single chip is 16 Kbytes (C000H to FFFFH) the PROM can be programmed

as follows:

• Programming procedure

(1) Set the EPROM programmer to the MB89P195.

(2) Load program data into the EPROM programmer at 4000H to 7FFFH. (note that addresses 0C000H to 0FFFFH

in the operation mode correspond to 4000H to 7FFFH in EPROM mode.)

(3) Program with the EPROM programmer.
