Section 18 ROM
18.3.1
An efficient, high-speed programming procedure can be used to program and verify PROM data.
This procedure programs the chip quickly without subjecting it to voltage stress and without
sacrificing data reliability. Unused address areas contain H'FF data. Figure 18.4 shows the basic
high-speed programming flowchart. Tables 18.5 and 18.6 list the electrical characteristics of the
chip during programming. Figure 18.5 shows a timing chart.
