8.1.8 PAD/ASYNC/External Reset Port

The PAD port (Program Associated Data) relays information which is carried along with the audio data
received. i.e. song and artist information, or relay cues to trigger events. Table 37 provides the PAD /
ASYNC port specifications, and Table 38 contains the pin-out table for the PAD port. In addition, this
connector has an optical input that can be used to cause a hard power reset to the receiver. The
hardware reset feature is disabled by default and can be enabled in software. If enabled, connecting the
optical input to ground will activate a hardware reset.
