PROM Programming

The write/verify specifications in PROM mode are the same as for the standard EPROM
HN27C101. Page programming is not supported, so do not set the PROM programmer to page
programming mode. Naturally, PROM programmers that only support page programming mode
cannot be used. When selecting a PROM programmer, check that the byte-by-byte high-speed,
high-reliability programming method is supported.

Selecting the Programming Mode

There are two on-chip PROM programming modes: write and verify (which reads and confirms
the data written). Use the pins to select the modes (table 17.2).
