3.2.4.10.3 ARM SPI
This SPI interface is controlled by OMAP's ARM core. Devices connected to this bus include MAKO,
display controllers and the audio CODEC.
3.2.4.10.4 DSP SPI
This SPI interface is controlled by the DSP core of the OMAP processor. This bus is used to
configure and control devices on the RF deck.
3.2.4.10.5 I2C
The I2C bus of the OMAP processor controls the lighting controller IC. This bus is also available on
the bluetooth option board, routed via J3001.

SPI and I2C Configuration
3.2.4.10.6 1-Wire
The OMAP's 1-wire line is available on the GCAI pin 16. The signal is routed to the side connector
via J4001.
3.2.4.10.7 USB
The OMAP CPU's USB port is routed to the side connector via J4001. The USB signals on the side
connector are illustrated in
Figure 3-30, on page 3-41
