Programming and verification should be carried out using the same specifications as for the standard HN27C101 EPROM.
However, do not set the PROM programmer to page mode, as the H8S/2357 does not support page programming. A
PROM programmer that only supports page programming cannot be used. When choosing a PROM programmer, check
that it supports high-speed programming in byte units. Always set addresses within the range H'00000 to H'1FFFF.
