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!!!!
