3.7 IEBus Controller (
μ
PD178096 and 178098 only)
The
μ
PD178096 and 178098 have an IEBus controller. The functions of this IEBus controller are limited as
compared with the existing IEBus interface functions of the
μ
PD78098 subseries.
Table 3-3 compares the interfaces of the
μ
PD78098 subseries and
μ
PD178098 subseries.
