8-1 EPROM Versions
8-1-1 Overview
EPROM version is microcomputer which was replaced with the mask ROM of the MN101C11 with an electronically programmable
Because the MN101CP117**(**=DP,BF,HP) is sealed in plastic, once data is written to the internal PROM it cannot be erased.
Because the
Setting the EPROM version to EPROM mode, halts microcomputer functions, and the internal EPROM can be programmed. Refer to the EPROM mode pin diagram in figure
The specification for writing to the internal EPROM are the same as for a
used to perform read and write operations.

-Cautions on use of the internal EPROM
-Erasing written Data in Windowed
-Characteristics of EPROM Versions
-Writing to the Microcomputer with Internal EPROM
