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."
Band Select.
00 = 87.5–108 MHz (USA, Europe) (Default).
01 = 76–108 MHz (Japan wide band).
10 = 76–90 MHz (Japan).
11 = Reserved.
Channel Spacing.
00 = 200 kHz (USA, Australia) (default).
01 = 100 kHz (Europe, Japan).
10 = 50 kHz.
Volume.
Relative value of volume is shifted –30 dBFS with the VOLEXT 06h[8] bit.
VOLEXT = 0 (default).
0000 = mute (default).
0001 = –28 dBFS.
