Property 0x1201 FM_RSQ_SNR_HIGH_THRESHOLD
The FM_RSQ_SNR_HIGH_THRESHOLD property sets the high threshold, which triggers the RSQ interrupt if the
SNR 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
Units: dB
Property 0x1202 FM_RSQ_SNR_LOW_THRESHOLD
The FM_RSQ_SNR_LOW_THRESHOLD property sets low threshold, which triggers the RSQ interrupt if the SNR
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
Units: dB
