Selection Between SPI and CAN Interface
The SPI and CAN interface are muxed on the same lines on the AWR1642 device. Based on the
configuration, the user can select if the pins E14 and D13 must be connected to the 20-pin/HD connectors
to provide the SPI interface OR to the onboard CANFD PHY (U3). This selection is done by the S2 switch.
This switch is available on the board from Rev B onwards.
