PRELIMINARY
Notice:
This
is not
a final
specification.
Some
parametric
limits
are
subject
to change.
ROM AREA MODIFICATION FUNCTION
The internal ROM size and its address area of the M37733M4BXXXFP
can be modified by the memory allocation control register’s bit 0 shown
in Figure 3.
Figure 5 shows the memory allocation in which the internal ROM
size and its address area are modified.
Make sure to write data in the memory allocation control register as
the flow shown in Figure 4.
This ROM area modification function is valid in memory expansion
mode and single-chip mode.
When ordering a mask ROM, Mitsubishi Electric corp. produces the
mask ROM using the data within 32 Kbytes (addresses 00800016 –
00FFFF16). It is regardless of the selected ROM size (refer to MASK
ROM ORDER CONFIRMATION FORM.) Therefore, program “FF16”
to the addresses out of the selected ROM area in the EPROM which
you tender when ordering a mask ROM.
Address 00FFFF16 of this microcomputer corresponds to the lowest
address of the EPROM which you tender.
