3.7 BlueTooth Connector
M9328MX1ADS provides a 20-pin connector, P9, for interfacing
the MC9328MX1 with the MMM7400 RF (MC13180) Module.
The selection of the used interface is determined via software by
programming internal registers. Note on the schematic several zero
ohm resistors allow the user to reconfigure the pin out to
accommodate a different RF module. Figure 3-6 gives the pin
assignments and Table 3-6 gives the signal descriptions for this
connector.

* Controlled by zero ohm resistors. The inside signal is the one connected when
the system is shipped from the factory.
