Note: The V
The H8/3257 or H8/3256 PROM has the same standard read/write specifications as the HN27C101
EPROM. Page programming is not supported, however, so do not select page programming mode.
PROM writers that provide only page programming cannot be used. When selecting a PROM
writer, check that it supports the byte-at-a-time high-speed programming mode. Be sure to set the
address range to H’0000 to H’EFFF for the H8/3257, and to H’0000 to H’BFFF for the H8/3256.
