Note: The V
The H8/325 PROM uses the same, standard read/write specifications as the HN27C256 and
HN27256.
11.3.2 Writing and Verifying
An efficient, high-speed programming procedure can be used to write and verify PROM data. This
procedure writes data quickly without subjecting the chip to voltage stress and without sacrificing
data reliability. It leaves the data H’FF written in unused addresses.
