2.1.7 Bus Observation (J3 or J8/J14 or J19)

For the TCAN1046A footprint, the CANH and CANL lines are available to be observed on an oscilloscope via the J3 or J8 headers. The CAN1 bus is routed to the J3 header, with CANH on pin 3, CANL on pin 4, and pins 1, 2, 5, and 6 are connected to GND. The CAN2 bus is routed to the J8 header, with CANH on pin 3, CANL on pin 4, and pins 1, 2, 5, and 6 are connected to GND.

For the TCAN1046AV footprint, the CANH and CANL lines are available to be observed on an oscilloscope via the J14 or J19 headers. The CAN1 bus is routed to the J14 header, with CANH on pin 3, CANL on pin 4, and pins 1, 2, 5, and 6 are connected to GND. The CAN2 bus is routed to the J19 header, with CANH on pin 3, CANL on pin 4, and pins 1, 2, 5, and 6 are connected to GND.
