16.3
The write/verify specifications in PROM mode are the same as for the standard EPROM
HN27C101. The page program system is not supported, so do not set the PROM writer to the page
programming mode. Naturally, PROM writers that only support the page programming mode
cannot be used. When selecting a PROM writer, check that the high-speed, high-reliability
programming system for each byte is supported.
16.3.1
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 16.2).
