18.2.1
In writer mode the PROM versions of the H8/3337Y and H8/3334Y suspend the usual
microcomputer functions to allow the on-chip PROM to be programmed. The programming
method is the same as for the HN27C101, except that page programming is not supported.
To select writer mode, apply the signal inputs listed in table 18.2.
