Previous Version
Additionally, the internal ROM area can be modi-
fied by software.
Note. Internal ROM area can be modified. (Refer
to the section on ROM area modification
function.)
The CPU operates on an internal clock
φ’s fre-
quency which is obtained by dividing the external
clock frequency f(XIN) by two.
The internal ROM size and its address area of the
M37733MHBXXXFP 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.
