Note: The AWR2243 does not support CAN communication. Because the AWR2243BOOST shares
the same PCB as the AWR1443BOOST, the PCB contains a CAN connector (J3) and CAN PHY (U3);
however, the connector and PHY are not functional. The SPI/CAN selector switch (refer to
Section 2.7.4 for more details)
should always be set to ‘SPI’ mode on the AWR2243BOOST.
