*: Refer to section 3, Operating Modes.
With the PROM version, programs can be written in the same manner as with an ordinary
EPROM by setting the LSI to PROM mode and using a standard EPROM writer.

21.2.1
PROM Mode Settings
When programming the on-chip PROM, set the pins as shown in figure 21.2, 21.3, or 21.4, and
perform the programming in PROM mode.
21.2.2
Socket Adapter Pin Correspondence and Memory Map
Connect the socket adapter to the SH7040 series chip as shown in figure 21.2 or 21.3. This will
allow the on-chip PROM to be programmed in the same manner as an ordinary 32-pin EPROM
(HN27C101). Figures 21.2, 21.3, and 21.4 show the correspondence between the SH7040 Series
pins and HN27C101 pins. Figure 21.5 is a memory map of the on-chip ROM.
