20.4 Functional description
The M37703 has the same internal circuit as the M37702. The control registers in the SFR area and the
memory assignment are also the same. However, part of the M37703 functions varies from the M37702’s,
because the number of M37703’s pins is 64 pins.
Table 20.4.1 lists the differences between the M37703 and M37702.
This paragraph describes the differences from the M37702. Refer to the relevant functional descriptions of
the M37702 about others.
