2.4.2 Debug Connector-60 pin (J7)

This connector enables interfacing of LVDS signals to the DCA1000 EVM for data capturing purposes.

Also, the connector has SPI, I2C, JTAG, GPADC, WRMRST, NRROUT, EPWM, and other control signals from AWR2944EVM/AWR2944PEVM for debug purpose.

The SPI is multiplexed to the Debug Connector. For more details refer to Section 2.8.1.
