      Table 1-283.  Bit field encoding: BYPASS_N_ENUM
      Value Name Description
      1'b0 BYPASS_N_DISABLE_BYPASS The buffer in the negative half remains on the s
      1'b1 BYPASS_N_ENABLE_BYPASS bypass the buffer on the negative half of the sig
      Table 1-284.  Bit field encoding: ENABLE_N_ENUM
      Value Name Description
      1'b0 ENABLE_N_0 power down buffer in negative half
      1'b1 ENABLE_P_1 enable negative half of buffer

         

      It means: that Delta sigma negative input buffer can be enabled (BYPASS_N_DISABLE_BYPASS)  and powered down (1'b0 ENABLE_N_0) at the same time

         

      FUNNY THING IT's A DEFAULT STATE IN DIFFERENTIAL MODE!!!!

         

        How the DelSig can measure?
