Read/write specifications are the same as for the standard HN27C101 EPROM, except that page
programming is not supported. Do not select page programming mode. A PROM programmer that
supports only page-programming mode cannot be used. When selecting a PROM programmer,
check that it supports a byte-at-a-time high-speed programming mode. Be sure to set the address
range to H'00000 to H'1FFFF.
