2.7.6 TI 14-Pin JTAG Connector (J19)
This connector provides a JTAG interface shown in
XDS emulators. To use this interface, the JTAG lines to the onboard emulator (XDS110) must be disconnected;
this is done with S1 (12th position of DIP switch should be open), and the external emulator on the MIPI 60-pin
connector also must be disconnected.
2.7.7 CAN Connector (J1 and J2)
The J1 and J2 connectors shown in
FD transceiver (TCAN1042HGVDRQ1) and CAN transceiver (SN65HVDA540QDR) independently, as shown in
Figure
2-22. These signals are wired to the CAN bus after muxing with the SPI interface signals; one of the two
paths must be selected. Two CANs are selected by closing the switch S1 (1st position of switch to be ON).
