Property 0x1302 AM_ACF_CHBW_THRESHOLD
The AM_ACF_CHBW_THRESHOLD property sets the Channel Filter Bandwidth interrupt threshold in units of
100 Hz. When the Channel Filter Bandwidth falls below this threshold and the CHBW_INT interrupt is enabled
through the AM_ACF_INTERRUPT_SOURCE property, the CHBW_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

CHBW_THRESH_HIGH[7:0]
(Available in Si475x-A40 and later only)
Channel Filter Bandwidth High interrupt threshold in units of 100 Hz,
which triggers the Channel Filter Bandwidth Interrupt when the
channel filter bandwidth rises above this threshold.
Default is 0 kHz. Range is 0–255.
7:0
CHBW _THRESH[7:0]
Channel Filter Bandwidth Low interrupt threshold in units of 100 Hz,
which triggers the Channel Filter Bandwidth Interrupt when the
Channel Filter Bandwidth falls below this threshold.
Default is 0 kHz. Range is 0–255.
