SPI Bus Interface

This bus is a synchronous serial bus made up of a data, a clock, and an
individual IC unique select line. It's primary purpose is to configure
the operating state of each IC. ICs programmed by this include;
display module, ADSIC, Fractional N Synthesizer, Pendulum Reference
Oscillator, DAIC, and if equipped, the secure module.

The MCU (U204) is configured as the master of the bus. It provides the
synchronous clock (SPI_SCK), a select line, and data (MOSI [Master
Out Slave In]). In general the appropriate select line is pulled low to
enable the target IC and the data is clocked in. Actually the SPI bus is
a duplex bus with the return data being clocked in on MISO (Master In
Slave Out). The only place this is used is when communicating with
the secure module. In this case, the return data is clocked back to the
MCU on MISO (master in slave out).

Universal Connector
and Option Selects

The universal connector is located on the back of the radio. It is the
external port or interface to the outside and is used for programming
and interfacing to external accessories. The signals are outlined in the
following diagram. The universal connector connects to the VOCON
board at J201 through a flex circuit routed down the back of the
external housing. Connections to the universal connector and J201 on
the VOCON board are shown in Figure 9 and Figure 10.
