19.5.2
An efficient, high-speed programming procedure can be used to program and verify PROM data. This procedure writes
data quickly without subjecting the chip to voltage stress or sacrificing data reliability. It leaves the data H'FF in unused
addresses. Figure 19-4 shows the basic high-speed programming flowchart. Tables 19-7 and 19-8 list the electrical
characteristics of the chip during programming. Figure 19-5 shows a timing chart.
