Property 0x1205 FM_RSQ_ISSI_HIGH_THRESHOLD
The FM_RSQ_ISSI_HIGH_THRESHOLD property sets the Image Signal Strength Indicator high threshold, which
triggers the RSQ interrupt if the ISSI is above this threshold. 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: 127
Property 0x1206 FM_RSQ_ISSI_LOW_THRESHOLD
The FM_RSQ_ISSI_LOW_THRESHOLD property sets the Image Signal Strength Indicator low threshold, which
triggers the RSQ interrupt if the ISSI is below this threshold. 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: –128
