20.6 PROM version
In the PROM version, programming to the built-in PROM can be performed by using a general-purpose
PROM programmer and a programming adapter, which is suitable for the used microcomputer.
The PROM version of M37703 is the one time PROM version. Programming to the PROM can be performed
once in this version.
The one time PROM version has the same functions as the mask ROM version except that the former has
a built-in PROM. Table 20.6.1 lists the write address of PROM version.
The M37703 does not have the EPROM version. Use the EPROM version of M37702 with a pitch converter
for the M37703 evaluation.
Table 20.6.1 Write address of PROM version
Notes 1: Refer also to section “20.6.2 Bus timing and EPROM mode.”

20.6.1 EPROM mode
The EPROM mode of M37703 is the same as the M37702’s. Refer to section “19.2 EPROM mode.”
The pin connections vary from the M37702’s. Figure 20.6.1 shows the pin connections in EPROM mode.
2: A blank product of the one time PROM version does not have the ROM number, which is printed
on the XXX position. For example, M37703E2BSP.
