FR0..3=1: All channel filters and gain blocks are configured as defined in the ringing
state
FR0..3=0: All channel filters and gain blocks are configured as defined with the
programmed value if also the corresponding FD bit is set to 0
FD0..3=1: All channel filters and gain blocks are configured as defined in the default
state if also the corresponding FR bit is set to 0
FD0..3=0: All channel filters and gain blocks are configured as defined with the
programmed value if also the corresponding FR bit is set to 0
