Property 0x0710 AM_AGC_OVERRIDE
The AM_AGC_OVERRIDE property overrides the AGC setting by disabling the AGC and forcing the gain to be
maximum. 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: 0x0000
Property 0x071B AM_AGC_RSSI_OFFSET
The AM_AGC_RSSI_OFFSET property sets the value of the offset applied to the RSSI value in order to account
for the front-end gain/loss due to the AGC. 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.
Si475x-A10 and earlier: This property is not available.
Si475x-A20 and later, Default: 0
