Left Input PGA Common Mode Rejection enable
0 = Disabled
1 = Enabled
(only available for L_MODE=01 – Differential Line)
In Single-Ended or Differential Line Modes, this field
selects the input pin for the inverting side of the left
input path.
In Differential Mic Mode, this field selects the input
pin for the non-inverting side of the left input path.
00 = IN1L
01 = IN2L
1X = IN3L
In Single-Ended or Differential Line Modes, this field
selects the input pin for the non-inverting side of the
left input path.
