Property 0x1303 FM_ACF_HICUT_THRESHOLD
The FM_ACF_HICUT_THRESHOLD property sets the HICUT interrupt threshold in units of 100 Hz. When the
HICUT cutoff frequency falls below this threshold and the HICUT_INT interrupt is enabled through the
FM_ACF_INTERRUPT_SOURCE property, the HICUT_INT interrupt will be asserted. 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: 0
Units: 100 Hz
