Property 0x351B FM_BLEND_CHBW_RELEASE_TIME
The FM_BLEND_CHBW_RELEASE_TIME property sets the transition time for which the stereo blend mitigation
engine increases the stereo separation based on channel bandwidth. The CTS bit (and optional interrupt) is set
when it is safe to send the next command. This property may only be set or read in powerup mode.
Default: 1
Units: ms
Property 0x3600 FM_HICUT_RSSI_THRESHOLDS
The FM_HICUT_RSSI_THRESHOLDS property sets the RSSI thresholds for HICUT to begin band limiting and
reach maximum band limiting on L+R channel based on max and min cutoff frequency (set by Property 0x3601) on
the HICUT engine. The CTS bit (and optional interrupt) is set when it is safe to send the next command. This
property may only be set or read in powerup mode.
Default: 0x230F
Units: dBµV
