ROM PROGRAMMING METHOD
The built-in PROM of the blank One Time PROM version can be
read or programmed with a general-purpose PROM programmer
using a special programming adapter. Set the address of PROM
programmer in the user ROM area.
The PROM of the blank One Time PROM version is not tested or
screened in the assembly process and following processes. To en-
sure proper operation after programming, the procedure shown in
Figure 54 is recommended to verify programming.
