Data Port Interface

Bit 7 .. Bit 5:Signed Magnitude Offset for all steps of course AGC. Saturation threshold is 4+ value where V=3<Value<3.

Bit 4: A value of ‘1’ allows the AGC algorithm to retrigger with ADC saturation.

Bit 3: A value of ‘1’ enables the alternate TX/RX data bus interface.

Bit 2: Reserved, set to ‘0’.

Threshold

Bit 7: LNAGs Delay-When set to ‘1’, this delays the next AGC decision step an extra 1µS (total of 2µS) if a transition

of the LNAGs pin from 1 to 0 occurs.

Bit 6 .. Bit 3:Reserved, set to ‘0’.

Bit 2: Sets threshold for AGC re-trigger.

‘0’ sets re-trigger threshold to high count.

‘1’ sets re-trigger threshold to low count.

Bit 1: Reserved, set to ‘0’.

Bit 0: Reserved, set to ‘0’.
