Blend Detect Interrupt.
0 = Blend is within the Blend threshold settings.
1 = Blend goes above or below the Blend threshold settings.
Multipath Detect High (Si4706/40/41/49 Only).
0 = Detected multipath value has not exceeded above the Multipath high threshold.
1 = Detected multipath value has exceeded above the Multipath high threshold.
Multipath Detect Low (Si4706/40/41/49 Only).
0 = Detected multipath value has not fallen below the Multipath low threshold.
1 = Detected multipath value has fallen below the Multipath low threshold.
SNR Detect High.
0 = Received SNR has not exceeded above SNR high threshold.
1 = Received SNR has exceeded above SNR high threshold.
SNR Detect Low.
0 = Received SNR has not fallen below SNR low threshold.
1 = Received SNR has fallen below SNR low threshold.
RSSI Detect High.
0 = RSSI has not exceeded above RSSI high threshold.
1 = RSSI has exceeded above RSSI high threshold.
RSSI Detect Low.
0 = RSSI has not fallen below RSSI low threshold.
1 = RSSI has fallen below RSSI low threshold.
Soft Mute Indicator.
Indicates soft mute is engaged.
AFC Rail Indicator.
Set if the AFC rails.
Valid Channel.
Set if the channel is currently valid and would have been found during a Seek.
Pilot Indicator.
Indicates stereo pilot presence.
Stereo Blend Indicator.
Indicates amount of stereo blend in% (100 = full stereo, 0 = full mono).
