Previous Version
The internal ROM size and its address area of the
M37735MHBXXXFP can be modified by the
memory allocation control register’s bits 0,1 and 2
shown in Figure 70.
Figure 72 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 71.
This ROM area modification function is valid in
memory expansion mode and single-chip mode.

Revised Version
The internal ROM size and RAM size of the
M37735MHBXXXFP can be modified by the
memory allocation control register’s bits 0,1 and 2
shown in Figure 70.
Figure 72 shows the memory allocation in which
the internal ROM size and RAM size are modified.
Make sure to write data in the memory allocation
control register as the flow shown in Figure 71.
This ROM area modification function is valid in
memory expansion mode and single-chip mode.
Table 12 shows the relationship between the
memory allocation selection bits and addresses
______
corresponding to chip-select signals CS0 and CS1.
