EPROM MODE

The built-in PROM of the blank One Time PROM version and built-

in EPROM version can be read or programmed with a

general-purpose PROM programmer using a special programming

adapter. The One Time PROM version and the built-in EPROM

version have the function of the M5M27C101 corresponding for

writing to the built-in PROM. Set the address of PROM program-

mer 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 65 is recommended to verify programming.
