Pin 8 of the transceiver is normally a status indicator flag (nFAULT) or a SPI clock pin (SCLK). The signal path to the J2 header is pre-installed with a 100 nF filtering capacitor, C15. An optional pulldown resistor to GND can be installed on R21, and an optional pullup resistor to VIO can be installed on R19. Additionally, diode D2 signifies whether pin 8 is high or low. Note that the diode is inverted.
