3.6 TXD Input

The TXD input pin is how messages are transmitted to the bus through the TCAN1145-Q1 CAN transceiver. TXD can be accessed on pin 5 of the J11 jumper, and has a pull-up to VIO populated by default. This pull-up is not necessary for proper function, but if needed can be added by populating R16. There is also a footprint for a filter capacitor if desired by the user.
