BUILT-IN PROM VERSION

7733 Group User’s Manual

19-2

In the PROM version, programming to the built-in PROM is possible by using a general-purpose PROM

programmer and a programming adapter which is suitable for the microcomputer.

The built-in PROM version has the following two types :

qOne Time PROM version

Programming to the PROM is possible once.

This version is suitable for a small quantity of and various production.

qEPROM version

Programming to the PROM is possible repeatedly because a program can be erased by exposing the

erase window on the top of the package to an ultraviolet light source.

This version can be used only for program development (Evaluation only).

The built-in PROM version differs from the mask ROM version in the following:

• The built-in PROM version has a built-in PROM.

• Bit 3 of the oscillation circuit control register 1 (address 6F16) of the built-in PROM version is “1” at reset.

• Bit 3 of the oscillation circuit control register 1 (address 6F16) of the built-in PROM version must be fixed

to “1.”
