Mode 7 (PROM mode)

When the SH7034 is set to PROM mode, programs can be written in the PROM version in the

same way as with ordinary EPROM, using a general-purpose EPROM programmer.

PROM Mode

To program the on-chip PROM, set the pins as shown in figure 17.2 and use the chip in PROM

Mount the socket adapter on the SH7034 as shown in figure 17.2. This allows the on-chip PROM

to be programmed in exactly the same way as ordinary 32-pin EPROMs (HN27C101). Figure 17.2

shows the correspondence between SH7034 pins and HN27C101 pins. Figure 17.3 shows the

memory map of the on-chip ROM.

The address range of the HN27C101 (128 kbytes) is H'00000–H'1FFFF. The on-chip PROM (64

kbytes) is not found in the latter half (H'10000–H'1FFFF).

When programming with a PROM programmer, the program address range must be set to H'0000–

H'FFFF. The data for the H'10000–H'1FFFF address area should all be H'FF. Set byte mode, not
