3.5 RXD Output

The RXD output pin is how messages are received from the bus through the transceiver. RXD can be accessed using the main digital IO jumper. There is an optional pull-up resistor for this signal that may be populated to bias the pin state when the signal driver is not active. There is also a footprint for a filter capacitor if desired by the user.
