MC1320x MCU Interface
Figure 4-1
shows the typical connections between the MC1320x transceiver and a microcontroller unit
(MCU). See the
MC13202/203 Reference Manual
, document MC13202RM, for interface considerations.
Details about the interconnects for both the GB60 and M52235 Development boards are described in
Section 5.1, “Development Board Interconnects”
.
