Enables the penultimate LSB bit to be used for control
information, so that Peak detector output can be sent on it. the
LSB position is dependent on 12bit or 16bit mode of operation
accordingly. Penultimate LSB of I contains detector selected
by rx_agc_pin_3_select_bits. Penultimate LSB of Q contains
detector selected by rx_agc_pin_4_select_bits
