15. PROM PROGRAMMING METHOD
The built-in PROM of the One Time PROM version (blank) and the
built-in EPROM version can be read or programmed with a general-
purpose PROM programmer using a special programming adapter.
The PROM of the One Time PROM version (blank) is not tested or
screened in the assembly process nor any following processes. To
ensure proper operation after programming, the procedure shown in
Figure 15.1 is recommended to verify programming.
