D102: (YELLOW) PPS Indicator (blinking).
D102 LED is supplied by VCC_2V8 but LED supply is controlled by PPS output signal from AirPrime
XM0110. This signal is under AirPrime XM0110 firmware control. The PPS signal will provide pulse
output only once GPS acquisition reaches sufficient accuracy to provide a reliable period. In
particular, this requires a GPS fix to be obtained. Until such conditions are achieved, no signal will be
output at PPS pin.
