15:8 SEEKTH[7:0] RSSI Seek Threshold.

0x00 = min RSSI (default).

0x7F = max RSSI.

SEEKTH presents the logarithmic RSSI threshold for the seek operation. The

Si4702/03-C19 will not validate channels with RSSI below the SEEKTH value.

SEEKTH is one of multiple parameters that can be used to validate channels. For

more information, see "AN284: Si4700/01 Firmware 15 Seek Adjustability and Set-

tings."
